Answer
Both A and R are true and R is the correct explanation of A.
Explanation — Meanders are the result of both erosion and deposition work of rivers. Meanders generally form under conditions of a gentle slope and sufficient water in rivers. The river flow is diverted by an obstruction allowing the river to do lateral erosion work.
