Explanation
Assertion (A) is correct. Historically, the Teesta River was a tributary of the Ganga, flowing through the Karatoya and Atrai channels. However, following the catastrophic floods of 1787, the river diverted its course eastward to join the Brahmaputra (Jamuna) in Bangladesh. Reason (R) is also correct. Himalayan rivers are characterized by high sediment loads, steep gradients, and tectonic instability, making them prone to river capturing (river piracy) and frequent course changes (avulsion). The shifting of the Teesta is a classic example of this dynamic geomorphological behavior. Since the inherent nature of Himalayan rivers to change course or capture drainage explains why the Teesta shifted from the Ganga to the Brahmaputra system, (R) is the correct explanation of (A).
