Solution

The correct option is C Towards north east direction

In order to cross the river in the shortest possible time, the person should swim perpendicular to the direction of flow of the river. From the figure, we can see that the direction perpendicular to the direction of flow of the river is the North-East direction. Hence the correct option is (c).
