💡 Detailed Explanation
The man is asking you to review a document by the end of the day. The most natural response is to politely decline because you are busy and offer an alternative, which is to do it tomorrow. Option 2 is incorrect because he just asked you, so you couldn't have already read it. Option 3 is incorrect because the request is to 'look over' (目を通す), not to 'create' (作成する) the document.
