Final answer:
Neutrons do not experience electromagnetic repulsion because they are neutral particles, unlike protons that experience it due to their positive charge.
Step-by-step explanation:
The correct answer is Option B) Electromagnetic repulsion.
Neutrons do not experience electromagnetic repulsion because they are neutral particles that do not possess an electrical charge. While protons, which are positively charged, experience electromagnetic repulsion due to the electrostatic force between them. The strong force is responsible for holding the nucleus of an atom together, despite the repulsive electromagnetic force between protons.
