Thus, B is the correct answer.

Tropical deciduous forests are the most widespread forests of India. They are also called the monsoon forests and spread over the region receiving rainfall between 200 cm and 70 cm. Trees of this forest-type shed their leaves for about six to eight weeks in dry summer. On the basis of the availability of water, these forests are further divided into moist and dry deciduous. The former is found in areas receiving rainfall between 200 and 100 cm. There are open stretches in which Teak, Sal, Peepal, Neem grow.

Most common among males, haemophilia is characterized by a deficiency in blood clotting leading to abnormal bleeding. The haemophilia gene is located on the X chromosome that encodes gender. Since males have an X and a Y chromosome, they inherit only one copy of the X chromosome (from their mother). So, if their mother is a carrier of the mutated gene, they have a better chance of inheriting haemophilia. Females have two X chromosomes (one from their mother and one from their father), and one usually has a normal copy of the gene. This means most women with the gene mutation are carriers but have no signs or symptoms of the disease.

All the above factors are responsible for formation of soil.

Soil is the uppermost layer of the land surface that plants use and depend on for nutrients, water and physical support. Five factors control the formation of soil viz. parent rock, relief, time, climate and plant and animal organisms.

Weathering of parent rock into tiny pieces is first step of the formation of soil.

Relief affects the degree of erosion of the parent rock material for example steep slopes are subjected to more rapid run-off of surface water than the gentle slopes. Therefore, there is less infiltration of water on steeper slopes, which retards soil forming processes.

Time also affect process of soil formation. A well developed soil is an end product of physical, chemical and biological weathering for a very long period of time.

The process of weathering is directly linked with the seasonal change of temperature and distribution and nature of precipitation. Hence, climate plays an important role in soil forming processes.

Dead plants and animals contribute to the organic content of the soil. Hence, plant and animal organisms play important role in formation of soil.
