💡 Detailed Explanation
The speaker is making an urgent request. The most appropriate response is to agree to the request and state that you will do it immediately. 'はい、承知しました。すぐ確認します。' (Yes, understood. I'll check it right away.) is a polite and direct acceptance. 'いえ、こちらこそ、よろしくお願いします。' is a response to someone else's greeting or introduction. 'はい、もう目を通したばかりです。' incorrectly assumes the question was about whether you have already finished the task.
