Solution
The correct option is C Assertion is correct but Reason is incorrect Ocean waves are transverse waves travelling in concentric circles of the ever-increasing radius. When they hit the shore, their radius of curvature is so large that they can be treated as plane waves. Hence they hit the shore nearly normal to the shore.
