When the Plate Area of a Capacitor Increases

Answer: Option A. 

When the plate area of a capacitor increases, the capacitance also increases.

Solution

The capacitance of a parallel plate capacitor is 

C=ϵA/d

Where A is the cross-sectional area of the plates 

d is the distance between the parallel plates

ϵ is the permittivity of dielectric material.

Capacitance (C) is directly proportional to the plate area of a capacitor.

Therefore, when a plate area of a capacitor increases, the capacitance also increases.
