Given below are two statements, one is labelled as Assertion (A) and the other as Reason (R).
Assertion (A) : In the Himalayan mountains different types of vegetation are found.
Reason (R) : In Himalayas, there are variations in climate with change in altitude.
Select the correct answer from the code given below :
Code :

A

(A) is false, but (R) is true

B

Both (A) and (R) are true and (R) is the correct explanation of (A)

C

Both (A) and (R) are true, but (R) is not the correct explanation of (A)

D

(A) is true, but (R) is false

Result

Your answer: — · Correct: B

Explanation

The Himalayan mountains exhibit a distinct vertical zonation of vegetation, ranging from tropical deciduous forests at the foothills to alpine meadows at higher altitudes. This diversity is primarily driven by the variation in climate that occurs with changing elevation. As altitude increases, there is a significant decrease in temperature (the normal lapse rate) and changes in precipitation patterns. These climatic shifts create different ecological niches, allowing for a succession of vegetation belts: tropical, sub-tropical, temperate, and finally alpine. Therefore, both the assertion and the reason are correct, and the reason provides a direct scientific explanation for the assertion.
