So is there a solution or not?
I don't understand the given answer... someone explain.
C simply has to wait a few seconds to see if D can answer or not.LockerFish wrote:

If D can answer then it is only because the two hats in front of him (B and C) are the same color. If this is the case then D knows for certain that his own hat is the opposite color.
If D has not answered in a few seconds, then C can assume that it is because he is unable to answer accurately. As so, B and C must have two different colored hats.
C then knows that his hat is not the color that B's hat is, and can answer knowing for certain of the color of his own hat.
