Q. Assertion (A): River Kalinadi is an east-flowing river in the southern part of India. Reason (R): The Deccan Plateau is higher along its western edge and gently slopes towards the Bay of Bengal in the east.
Answer: (A) is false but (R) is true.
Notes: Assertion (A) is false. There is no major river named Kalinadi that is east-flowing in southern India; Kalindi refers to the Yamuna River (a Ganga tributary in north India) in Hindu texts like Mahabharata. The actual Kalinadi River (also Kali Nadi) flows westward from Karnataka (Western Ghats) to the Arabian Sea in Goa, not east to the Bay of Bengal. Reason (R) is true, as the Deccan Plateau slopes eastward, causing peninsular rivers like Godavari and Krishna to flow east. Since (A) is false and (R) is true, the code is (d).
