Choose the correct option which contains the law for which Maxwell introduced the concept of displacement current to resolve the conceptual contradiction.

Maxwell pointed out the ambiguity of the circuital rule of Ampere, as that rule referred to an electrical circuit with a capacitor, it tended to be wrong or incomplete. Since, no current was presumed in the gap between the capacitor plates. 

Maxwell said that there is also a current flow in the gap between the plates of the capacitor known as displacement current which is due to a time varying electrical field between the plate.
