Solution

The correct option is D Both Assertion and Reason are incorrect
A physical quantity is said to be a vector only if it has both magnitude as well as direction.
Thus if the magnitude of displacement is zero, then it is not said to be a vector quantity.
Hence both the statements are correct and the reason explains the assertion very well.
