Why is A not correct?

I thought that A was correct from this logic:
not ED--> not PW
PW--> ED
Please elaborate as to why this is not correct. Thank you!

Hi, the original argument is If not both X and Y, then not Z. Mary has both X and y, so she will have Z. This is far from the logic of A, which is If not X or Y, then not Z. Paul has Z, so must have X and Y.
