उत्तर
Both A and R are true, and R is the correct explanation of A.
Explanation:
River meanders are bends in the longitudinal course of a river. They form due to erosion on the outer banks and deposition on the inner banks, which occurs under conditions of a gentle slope and sufficient water. This process explains why meanders develop in rivers with a low gradient and ample flow, making the reason a valid explanation for the assertion.
