If C was close to all-in or possibly tilting, I think you should call. If he's playing sort of weak-tight (which I think was probably the case from your description) then a fold is in order.

Given the situation, I think your laydown was correct. You are beat the vast majority of the time here, and if rags flop, you get put in the situation of having to pay-off unless there is heavy action from the others.
