Actually, e.) is a valid statement according to the Law of Syllogism.

It's b.)

If I shower in the morning, then I do not smell bad.

I do not smell bad.

You cannot make any valid conclusion because either "I showered in the morning" or "I didn't shower in the morning" makes the first premise true.
