Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
$K E = \frac{p^{2}}{2 m}$
For two bodies with same momentum, KE is inversely proportional to m
So, the assertion is correct

Also, $K E = 0.5 \times m v^{2}$
Thus, reason is also correct

But Reason is not the correct explanation of Assertion

Hence, correct answer is option $B$
