Answer:
c. Induced voltage.
Explanation:
Faraday's law says
[tex]\varepsilon = N \dfrac{d \Phi_B}{dt},[/tex]
or in words,
"A changing magnetic flux induces an emf (potential difference) in a coil of wire "
This potential difference is induced, and therefore, we can also call it "induced voltage"; Hence, from the choices given, choice C stands correct.
P.S: Another tempting choice is d; however, it is incorrect since induced emf is NOT an electrostatic force.
