a.for b.with c.on d.to
I think that best answer is a.But It didn't match its answer.Its answer is d.But I don't think so.Why is d?

Answer 1

Yes, it is "d" -- there is no good explanation because this is an idiom. Idioms are word groups that go together, but no one knows why. They are usages that have been in existence for a long time, and no one remembers why it's considered correct, but other combinations of words are not.
