💡 Detailed Explanation
The phrase 'お勉強していただける (obenkyou shite itadakeru)' is a very indirect and polite way of pointing out someone's lack of knowledge or preparation on a topic and requesting they research it further. It's a soft form of criticism. The correct response is to acknowledge this feedback professionally, apologize for the oversight, and promise to take action. '申し訳ありません。至急、確認いたします (I'm very sorry. I will look into it immediately)' is the most appropriate professional response. The other options miss the nuance: one takes the word 'study' literally ('Yes, I'm good at studying'), and the other is a direct and rude refusal ('No, I'm fine without studying').
