Final answer:
Negative and positive charges attract each other due to the electrostatic force, as described by Coulomb's law. So, the correct answer from the given option will be Option A.
Step-by-step explanation:
When a negative charge and a positive charge are held close together and then released, they will attract each other. This is because Coulomb's law states that unlike charges attract one another, similar to how a negatively charged rod would attract the positive charges in a nearby object. The positive and negative charges will move towards each other due to this attractive electrostatic force.
