C答中了。A和B一定答不到因看不到其他人。
- G* Q" l: T- i/ M# \, @7 H5.39.217.77:8898假設C和B是同一顏色, 那D就會立刻知道自己的顏色，7 N: o8 \& h2 t  S* m; v; d* }
而不會過了一會才作答，C發現D不知道答案時就表示5.39.217.77:88985 ^2 t# O2 W+ ~9 n- j* R

C, because he saw B's hat is white and he knows D can see the color of B's and his hat. If B and his hat has the same color, D would speak out. But D kept silent, so C knows that his hat's color must be different.
