Detailed Solution

Acid chloride is treated with Grignard’s reagent it fails to give ketone but in case of Di alkyl cadmium it gives ketone. The bond polarity for $C d$ is less compared to $M g$ Hence, ketone is easily obtained with Di alkyl cadmium not with $M g$ where polarity is higher hence reaction does not takes place.

Therefore, both the statement (A) and (R) are true and (R) is the correct explanation of (A)

Hence, Option A is correct
