Answers:
Thoppi Thoppi ... (Hat)
Fisherman C shouts out.
Fishermen A and B are in the same situation - they have no information to help them determine their hat colour so they can’t answer. C and D realise this. Fisherman D can see both B and C’s hats. If B and C had the same colour hat then this would let D know that he must have the other colour. But he can't be sure. When the time is nearly up, C realises that D isn’t going to answer because he can’t. C realises that his hat must be different to B’s otherwise D would have answered. C therefore concludes that he has a black hat because he can see B’s white one.
