Answer/Explanation: When a negatively charged object is brought near the knob of a neutral electroscope, the negative charge repels the electrons in the knob, and those electrons move down the stem into the leaves. Excess electrons flow from the rod into the ball, and then downwards making both leaves negatively charged.

The electricity charge is a property of matter. It creates a force that takes place when placed in an electrical magnetic field they can be positive or negative. They are carried by the protons and electrons the charge is a conserved property.

Hence the option A is correct. Object B gets a negative charge.
