How is capacitance related to the distance between the plates of a capacitor?

For a parallel-plate capacitor, capacitance is given by C = εA/d, where ε is the material’s permittivity, A is the plate area, and d is the distance between the plates. Because distance is in the denominator, increasing the distance decreases capacitance. Thus, capacitance is inversely proportional to plate separation, as choice A states.
