Explanation
Nucleophilic attack is by nucleophiles i.e. electron rich species. These species tend to donate their electron density by attacking the electron poor centre. In a ketone, a – CO group is present which is known as the carbonyl carbon. The nucleophiles attack on the carbon centre of the carbonyl as it is electro positive. Therefore, the correct answer is option (a) the carbon atom of the carbonyl
