I think B will be correct if the question says that he did not submit the list.

I prefer E in this case.

Since you mentioned required condition and sufficient condition, we start there. Filing is apparently a sufficient condition based on the question. Answer to B will help find out whether it is also a required condition. However, whether it is required is not relevant. Just make up an example:

Tom bought flight ticket from Baffalo to NYC. We think he is going to NYC. However, buying flight ticket is not a required condition. He can buy train ticket or just get a rental car. It is a sufficient condition but adequate to evaluate whether he is going. Whether it is required does not lend any help to this evaluation.
