Concept:The capacitance of a parallel plate capacitor depends on the formula $C = \frac{\varepsilon A}{d}$.Explanation:Here, $C$ represents capacitance, $\varepsilon$ is the permittivity of the dielectric material, $A$ is the area of each plate, and $d$ is the distance between the plates.For fixed area and permittivity, when $d$ increases, $C$ decreases.When $d$ decreases, $C$ increases.Thus, capacitance varies inversely with the distance between the plates.Answer:Option C: inversely as the distance between the plates.
