Answer:

C.  a stationary electric charge

Explanation:

No force is exerted by a magnetic field on a stationary electric charge.

Magnetic force is given by the Lorentz equation as  

F = q (v × B)

q = Amount of electric charge

v = velocity of charge

B = Magnetic flux

F = Magnetic Force

On a stationary electric charge, we know that velocity of charge is equal to zero then Magnetic force will also be zero.
