Answer 1

Answer: (A)

receive less rainfall.

The southern slopes of the Himalayan region are covered in thick vegetation as compared to the northern slopes of the same hills as it receives less rainfall.

The growth of vegetation depends upon the amount of sunlight and rainfall received. The southern slopes of the Himalaya receive more rain due to the south west monsoon winds which travel west along the southern slops. The northern slopes do not receive any such rainfall. So the southern slopes are covered with thick vegetation as compared to the northern slopes.
