PHYSICS A man crosses a river of width d. Current flow speed

PHYSICS A man crosses a river of width d. Current flow speed is v. Speed of swimmer relative to water is v. Man always heads towards the point exactly opposite to the starting point at the another bank (relative to water). Radius of curvature of the path followed by the swimmer just after he start swimming is (A) d (B) 2/2d (C) 2d (D) V2d
