Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Work done by a force $W = F S cos θ$
where $θ$ is the angle between force $F$ and distance moved $S$ .
Since the weight lifter is holding the weight, so distance moved by it is zero i.e. $S = 0$
$⟹ W = 0$
Thus option A is correct.
