Given below are two statements, one is labelled as Assertion (A) and other as Reason (R): Assertion (A): Teesta river was earlier a tributary of Ganga now it is a tributary of Brahmaputra. Reason (R): River capturing is a major feature of Himalayan rivers. Select the correct answer using the codes given below.
Verified Answer
A. Both (A) and (R) are true and (R) is correct explanation of (A)
B. Both (A) and (R) are true, but (R) is not correct explanation of (A)
C. (A) is true, but (R) is false
D. (A) is false, but (R) is true
Explanation:
The Teesta River indeed changed its course; historically, it flowed into the Ganga (or Padma), but due to tectonic activity and river capturing, it now flows into the Brahmaputra (Jamuna in Bangladesh). River capturing is a common geomorphological phenomenon in the Himalayas due to active tectonics and steep gradients. Thus, both statements are true, and R correctly explains A.
