The correct answer is option 4 i.e. Purusha Sukta.

The Purusha Sukta is the 90th hymn of the 10th Mandala of the Rigveda. It describes the sacrifice of the Purusha (primeval being), from whose body the four Varnas emerged: the Brahmanas from the mouth, Kshatriyas from the arms, Vaishyas from the thighs, and Shudras from the feet. This hymn provided the earliest scriptural basis for social hierarchy.

Other Options:

• Varna Sukta: This is a misleading term; there is no specific hymn titled "Varna Sukta" in the Rigveda that defines the social structure.

• Brahm Sukta: While there are hymns dedicated to Brahman (the ultimate reality), they focus on metaphysics and creation rather than the social division of the Varna system.

• Manas Sukta: This hymn generally deals with the "Mind" or consciousness and its connection to the divine, not with social classification or hierarchy.

The correct answer is option 1 i.e. Both (A) and (R) are true, and (R) is the correct explanation of (A).

The month of October is known for 'October Heat' in the Indian subcontinent is true because, as the Southwest Monsoon retreats (October-November), the clouds disappear, leading to a clear sky. This clear sky allows direct solar radiation to hit the ground, causing high temperatures. Simultaneously, because the rain has just ended, the soil is still wet (high humidity). The combination of high temperature and high humidity creates oppressive, sultry weather, popularly called 'October Heat'.

The correct answer is option 4 i.e. A-3, B-1, C-2, D-4.

The correct answer is option 3 i.e. It was a successful revolt against the Britishers.

 The rebellion, also known as India's First War of Independence, ultimately failed due to several factors. These included a lack of unified leadership, a common program, and widespread support from all sections of Indian society. The British, with their superior military technology, organization, and resources, were able to effectively suppress the rebellion. As a result, the British Crown took direct control of India, ending the rule of the East India Company.

Given all the other statements are true regarding the revolt of 1857.

The correct answer is option 4 i.e. Mica.

• Mica constitutes 4% of the Earth's crust and is commonly present in both igneous and metamorphic rocks. It is utilized in electrical instruments.
• Mica is composed of elements such as potassium, aluminum, magnesium, iron, and silica.
• The Earth's crust primarily consists of eight elements, namely oxygen, silicon, aluminum, iron, calcium, sodium, potassium, and magnesium, accounting for approximately 98% of the total composition.

The correct answer is option 3 i.e. A-2, B-3 ,C-1, D-4, E-5.

• (A) Highest Population Density → (2) Bihar: As per Census 2011, Bihar emerged as the most densely populated state in India with 1,106 persons per sq. km, overtaking West Bengal. While Delhi has a higher density among UTs, Bihar is the standard answer for "States."

• (B) Lowest Literacy Rate → (3) Dadra and Nagar Haveli: While Bihar has the lowest literacy among states (61.8%), Dadra and Nagar Haveli recorded the lowest literacy rate among all Union Territories at 76.24%.

• (C) Urban Population Share → (1) 31.16%: According to the 2011 data, the level of urbanization in India increased from 27.81% in 2001 to 31.16% in 2011.

• (D) 2nd Highest Literacy Rate → (4) Mizoram: Kerala ranks 1st (94%). Mizoram holds the 2nd position with a literacy rate of 91.33%.

• (E) Decadal Population Growth → (5) 17.64%: This represents the percentage increase in India's total population between 2001 and 2011. It showed a decrease from the previous decade's 21.54%.

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

The Pradhan Mantri Suraksha Bima Yojana (PMSBY) is an Indian government-backed accident insurance scheme launched on May 9, 2015.

The correct answer is option 1 i.e. Simple body.

Thallophytes, such as algae and fungi, are the simplest group of plants. They have a thallus, which is an undifferentiated plant body without true roots, stems, or leaves. These plants do not produce flowers or seeds and usually reproduce by spores. Thallophytes can be unicellular or multicellular but lack the complex structures seen in higher plants.

Other options:

Roots, true leaves, and flowers are absent in this group, which distinguishes them from bryophytes, pteridophytes, and flowering plants. Their simplicity allows them to thrive in moist or aquatic habitats, performing photosynthesis and other life processes in a minimalistic manner.

The correct answer is option 3 i.e. They do not have spaces in between them. 

Particles of matter, whether in solids, liquids, or gases, have specific characteristics. They are very small, constantly in motion, and attract each other due to intermolecular forces. However, it is not true that they do not have spaces in between them. In reality, particles always have some space between them, which varies depending on the state of matter. In solids, the spaces are very small, making them dense and rigid. In liquids, the spaces are slightly larger, allowing particles to flow. In gases, the spaces are much larger, which is why gases can be compressed easily.

Other options:

• They are very small: True — particles are microscopic.

• They are moving constantly: True — motion depends on temperature and state.

• They attract each other: True — attraction holds matter together.
