Answer:
C. Electromagnetic interactions
Step-by-step explanation:
All forces related to magnetism and charge is known as electromagnetic force.
as we know that the force between two charges is given by Coulomb's law which is given as
![F = \frac{kq_1 q_2}{r^2]]()
also we know that force on a moving charge is given as

so whenever there is force related to charge and magnet then it is considered as fundamental force given as
C. Electromagnetic interactions
