Solution

The correct option is C Assertion is correct but Reason is incorrect
Displacement is the shortest straight line distance between initial and final position.
Hence if a body travels along a random path to return to the point of start, the body has traveled finite distance, however the displacement of it is exactly zero.
Hence correct answer is option C.
