Hint: The Law of conservation of charge is easily observed in the induction charging process. When the negatively charged balloon gets close to the wall, the negative charge in the wall is repelled. When one object is rubbed against another, static electricity can be created.
Complete step by step solution:
On rubbing, the balloon collects electrons from the wall and makes it negative with respect to the wall and hence the balloon ceiling to the wall. While ceiling to the wall, the electrons on the balloon leaks off the balloon and eventually leaves. The balloon at the same potential as the wall, thus when the attraction between the balloon and the wall is less than the weight of the balloon, the balloon eventually falls off, When the balloon is negatively charged on rubbing with the wall.
This means that the wall is not positively charged. The balloon induces a charge of the opposite sign in the ceiling of the wall, causing the balloon and the ceiling to be attracted to each other. And it falls because its charge slowly decreases as it leaks to the ground. Some charges on the balloon could be lost due to the presence of positive ions in the surrounding atmosphere, which tends to neutralize the negative charges on the balloon.
Option $(B)$, The balloon eventually falls off the ceiling, is the answer.
Note: The rubbing creates a negative charge by electrons and to produce static electricity. Objects made of the rubber-like balloon, etc., are electrical insulators, they are resisting electric charges flowing through them.
