There are mainly four fundamental forces exist in universe.
1. Gravitational force : It is the attraction between two objects that have mass. Example: The Earth rotating around the sun.
2. Strong nuclear force: It is responsible to hold nucleons inside the nucleus. Example: Protons and neutrons being bound to a nucleus.
3. Weak nuclear force: It is reasonable for the radioactive decay: Example: radioactive decay of subatomic particles.
4. Electromagnetic force: It is carried by elecmagnetic fields composed of electric and magnetic field. Example: A current carrying wire produces electromagnetic force.
Therefore, option (d); a current carrying wire is the correct choice.
