💡 Detailed Explanation
The man is asking his colleague to look over some documents. The phrase '〜てもらえないかな' is a polite way to make a request. The most natural response is to willingly accept the request. Answer 1, 'Sure, no problem. I'll get it done tonight,' indicates acceptance and is appropriate. Answer 2 misunderstands '悪いんだけど' (Sorry to bother you) as 'Are these documents bad?'. Answer 3 reverses the roles, as if the speaker is the one making the request.
