"The captain is a handsome man."
Translation:Kaptan yakışıklı bir adam.
I think it should be, could you report it as an alternative translation suggestion?
I think 'erkek' is used to refer generally..'adam' is used to pinpoint a particular person.
The answer choice that contains 'erkek' starts with a wrong word which makes one exclude this choice. (Answer choices may have been changed since the question above was posed)
As a learner, I think it would be o yakışıklı captain bir adam. I'm not sure really.
