Q. Consider the following statements:

1. Krishna and Cauvery are east-flowing rivers, whereas Narmada and Tapti are west-flowing rivers.
2. While Krishna and Cauvery form deltas, no delta is formed by Narmada and Tapti.

Which of the above statements is / are correct?
Answer: Both 1 and 2
Notes: Krishna and Cauvery are east-flowing rivers that drain into the Bay of Bengal and form extensive deltas at their mouths. In contrast, Narmada and Tapti flow westwards into the Arabian Sea and do not form deltas; instead, they form estuaries. Thus, both statements are correct as per the physiography of Indian rivers.
