"It's you who buys" vs "It's you who buy"

(A) Do you mind if it's you who buys the tickets?
(B) Do you mind if it's you who buy the tickets?

Which one is grammatically correct?

(A) is correct.

A if the you is singular, B if the you is plural (and that would be awkward; the speaker would probably say "you guys" to make that clear). But A would be my first inclination.

You should be president of Antimoon, Uriel.

I'm holding out for "Empress". ;P

It is I who buys the ticket.
