Solution

The correct option is D A - 3, B - 4, C - 1, D - 2
$R M g X$ is Grignard reagent.

In Clemmensen reduction, $Z n - H g$ /conc. $H C l$ is used.

In Rosenmunds reduction, we use $H_{2} / P d - B a S O_{4}$ .

In Wolf-Kishner reduction, we use $N_{2} H_{4} / K O H / C H_{2} O H C H_{2} O H$ .

Hence, option $B$ is correct.
