Assertion: If the positon vector of a particle moving in space is given by `vecr=2thati-4t^(2)hatj`, then the particle moves along a parabolic trajector.
Reason: `vecr=xhati+yhatj` and `vecr=2thati-4t^(2)j`
`rArr y=-x^(2)`.
A. If both assertion `&` Reason are True `&` the Reason is a corrrect explanation of the Asserion.
B. If both Assertion `&` Reason are True but Reason is not correct explanation of the Assertion.
C. If Assertion is Trie but the Reason is False.
D. If both Assertion `&` Reason are false
