[word choice] "suit" or "fit"

[english-holic]

A: I'm really sorry but you don't seem to ________ for the job.
B: You're right. I don't really like this kind of work.

(a) suit
(b) aim
(c) fit
(d) seek

The answer is (a) "suit" on my text book.

I was wondering if (d) "fit" also could be the answer.

And, please explain why.

Thank you so much in advance.

I don't like any of them after 'to'. I would say 'You don't seem fit/cut out/suitable/ for the job'.
