They've gotta be positively charged. If the repel each other, they have to be the same charge, as well as the fact that any object they attract has to the opposite charge. If A is negative then B and C have to be positive. 

Explanation:

It is known that when two objects have same or like charges then the objects repel each other.

Whereas when two objects have opposite or unlike charges then the objects attract each other.

Therefore, if object A has a negative charge and it is attracted by both objects B and C then it means object B and C has a positive charge.

Also, objects B and C repel each other due to same charge which is positive charge.
