Solution

The correct option is B Both Assertion and Reason are true, but Reason is not correct explanation of the Assertion.
Retarted motion, means acceleration is in direction opposite to displacement.
$a = \frac{c h a n g e i n v e l o c i t y}{t i m e} = \frac{c h a n g e i n d i s p l a c e m e n t}{t i m e^{2}}$

Here, the reason is not satisfying the assertion.
