A is positively charged. Look for a statement that describes that.
Explanation:
If C is negative, and there is a repulsive force between B and C then B is also negatively charged.
If A & B were rubbed together then any mobile charge carriers (electrons) lost by A have been gained by B. They must therefore have opposite charges.
Thus A is positively charged.
