Answer: Option (C) is the correct answer.
Explanation:
A process where a charged object is brought near a neutral object and without touching each other an opposite charge tends to develop on the neutral object.
For example, when a negatively charged rod is brought near a metal ball then a positive charge tends to develop on the surface of metal ball.
As we know that like charges repel each other and opposite charges tend to attract each other.
Thus, we can conclude that the observation two objects are oppositely charged, would support that statement.
