Answer: e

Explanation:

I think it is e because if the father is normal than his X is healthy and so all his daughters who will get his X will be healthy as well because the illness is recessive. But the sons are going to take their mother X that is linked with this gene and they wont get their father's X, which would have kept them normal.
