(C) Given that $(2, 3)$ and $(4, 5)$ show repulsion,balls $2$ and $3$ have the same charge,and balls $4$ and $5$ have the same charge.Since $(1, 2)$,$(2, 4)$,and $(4, 1)$ show attraction,if $1$ were charged,it would have to have a charge opposite to $2$ and $4$. However,if $2$ and $4$ have opposite charges,$1$ cannot simultaneously attract both unless $1$ is neutral.When a neutral object is brought near a charged object,it experiences electrostatic induction,resulting in an attractive force regardless of the sign of the charge on the other object.Thus,ball $1$ must be neutral.

Five balls numbered $1$ to $5$ are suspended using separate threads. Pairs $(1, 2)$,$(2, 4)$,and $(4, 1)$ show electrostatic attraction,while pairs $(2, 3)$ and $(4, 5)$ show repulsion. Therefore,ball $1$ must be:
