Logic and Abstract Reasoning

Four prisoners are about to be executed. Three are on one cell and the fourth is on another cell. The guard teases them, that there is a possibility for them to escape prison. That is, by answering his question correctly (without talking to each other), but if one of them is wrong they’ll be executed on the spot. He let the prisoners face the wall. C can only see the wall, B can only see the back of C, A can see the back of B and C and D is on the other side and can only see the wall. The guard took out four hats 2 colored white and 2 colored black, and he put them on the head of each prisoner (where each don’t know what color of hat is on their head). Then the guard asked them, to guess what color of hat they are wearing. Prisoner A said; “my goodness I don’t know what I’m wearing”. Who can guess his hat correctly?
