A is the document made by copying down in writing something that you listen to, like audio tapes, an interview, or comments made during a meeting.

Tape is the answer.

Explanation:

Look, we always mention audio tapes, an interview or comment made during a meeting in a tape. And the question is what do you 'copy down' so you can only copy it in a tape as audio tapes cannot be copied in the notebook or any other stationary items.

Hope this helps

Have a nice day
