Solution

The correct option is D $I > I I > I I I$
Since alkyl group has $+ I$ effect, Hence greater the number of alkyl attached to the carbonyl group, its reactivity towards nucleophilic addition reaction decreases. Secondly, as the steric crowding on carbonyl group increases, the reactivity decreases accordingly.

$∴$ Correct reactivity order for reaction with $P h M g B r$ is:

Option D correct.
