B and D is neutral. A and C have opposite charges.

Explanation:

Opposite charges attract each other and similar charges repel each other. Furthermore, a neutral object is attracted to a charged object whether negative or positive.

- If the balls B, C, and D is attracted to A, then their charge is either opposite to that of A or neutral.

- If the balls B and D have no effect on each other, then both balls are neutral.

- If B is neutral and attracted to C, then ball C have opposite charges than A.

Finally, B and D is neutral. A and C have opposite charges. Whether they are positive or negative cannot be determined by the information given in the question.
