The correct answer is option 1 i.e. Ulchi Freedom Shield 24.

Annual Joint military training exercise “Ulchi Freedom Shield 24 Exercise” is being conducted in South Korea between the USA. The Exercise is being conducted by 51st Fighter Wing at Osan Air Base in South Korea. The major objective of the exercise is to improve Local Wing Readiness and strengthen Command and control.

The correct answer is Option 3 i.e. 1, 2, 3, and 4.

All the statements about Sundarbans National Park are correct. Sundarbans National Park is part of the world's largest delta formed by the Ganges, Brahmaputra, and Meghna rivers (Statement 1). It is famous for its population of Royal Bengal Tigers (Statement 2). Sundarbans is recognized as a UNESCO World Heritage Site (Statement 3). The park also extends into Bangladesh, where it is known as the Sundarbans Reserve Forest (Statement 4).

The correct answer is option 2 i.e. China.

Under the Charter Act of 1833, the East India Company’s monopoly on trade with China was abolished. This act allowed other British merchants and traders to engage in trade with China, ending the East India Company's exclusive rights. This change was part of broader reforms aimed at modernizing and regulating the administration of British India and expanding trade opportunities. The abolition of the monopoly was significant in opening up international trade and enhancing commercial activities in the region.

The correct answer is Option 3 i.e. 1, 2, and 4 only.

The National Food Security Act (NFSA) provides subsidized food grains to approximately 75% of the rural population and 50% of the urban population (Statement 1). It entitles pregnant women and lactating mothers to a maternity benefit of at least ₹6,000 (Statement 2). The Act includes provisions for State Food Commissions to monitor and evaluate its implementation (Statement 4). However, Section 40, not Section 39, pertains to State Governments making rules to implement the Act (Statement 3 is incorrect).

The correct answer is Option 2 i.e. 1, 2, and 4.

The correct statements about hemoglobin's role in respiration are:

1. Hemoglobin binds to oxygen in a cooperative manner.
2. Hemoglobin releases more oxygen in response to lower pH levels (Bohr effect).
3. Hemoglobin can transport both oxygen and carbon dioxide.

Therefore, the correct option is: 1, 2, and 4

Hemoglobin exhibits lower affinity for carbon dioxide compared to oxygen due to the larger size of the carbon dioxide molecule. This size difference prevents the stable binding and structural accommodation that hemoglobin achieves with smaller molecules like oxygen. Similarly, ammonia also shows lower affinity for hemoglobin for the same reason—it is a larger molecule that cannot bind as effectively to hemoglobin's binding sites designed for smaller molecules like oxygen.

The correct answer is Option 3 i.e. Labor Underutilization Rate.

The Labor Underutilization Rate combines both unemployment and underemployment rates to assess the extent of labor market inefficiency. It captures individuals who are unemployed and actively seeking work, as well as those who are employed but not fully utilizing their skills or working fewer hours than desired. This measure provides a more nuanced understanding of labor market dynamics beyond just unemployment, highlighting challenges such as part-time employment and mismatched skills that affect overall workforce productivity and economic output.

The correct answer is Option 1 i.e. Health, Education, and Living Standards.

The Multidimensional Poverty Index (MPI) measures poverty using various indicators that fall under three main categories: Health (such as nutrition and child mortality), Education (years of schooling and school attendance), and Living Standards (including access to electricity, sanitation, drinking water, flooring, cooking fuel, and assets). This comprehensive approach provides a broader understanding of poverty beyond income-based measures.

The correct answer is Option 3 i.e. Docosahexaenoic acid (DHA).

Docosahexaenoic acid (DHA) is the omega-3 fatty acid most efficient at crossing the blood-brain barrier and incorporating into brain cell membranes. DHA is crucial for brain structure and function, making up a significant portion of the phospholipids in neuronal cell membranes. It supports synaptic plasticity, neurogenesis, and anti-inflammatory processes within the brain. Adequate DHA levels are associated with cognitive health, making it vital for brain development and maintenance throughout life. Dietary sources include fatty fish, algae, and DHA-fortified foods.

The correct answer is Option 2 i.e. Diffraction.

When light passes through a narrow slit, the phenomenon observed is diffraction. This effect causes the light waves to spread out and interfere with each other, resulting in a pattern of alternating bright and dark bands on a screen placed behind the slit. The width of the bands and their spacing depend on the wavelength of the light and the width of the slit. Diffraction is a clear demonstration of wave behavior of light and occurs due to the bending of light waves around the edges of the slit.

The correct answer is Option 2 i.e. Vinayak Damodar Savarkar.

Veer Savarkar (Vinayak Damodar Savarkar) organized the revolutionary group called "Abhinav Bharat" in the early 20th century. Founded in 1904 in India, Abhinav Bharat aimed to promote revolutionary activities against British colonial rule through armed resistance and nationalist propaganda. Savarkar, a prominent figure in India's independence movement, emphasized the need for self-reliance and militant action. Abhinav Bharat played a significant role in inspiring nationalist sentiments and fostering a spirit of resistance among Indian youth during that period.
