C)weakly attracted

Due to charging by induction, and negative charge on the small metal ball, the end A of the rod will acquire charge opposite to that of the metal ball. Hence the end A of the rod will acquire positive charge. Also, since opposite charges attract each other, the negative metal ball and the positive charge on the end A of the rod will attract each other.

But, since a small amount of positive charge will be induced hence the ball and end A of the rod will be weakly attracted.
