Concept:The capacitance of a capacitor depends on the area of its plates.Explanation:For a parallel-plate capacitor, the capacitance is given by $C = \frac{\varepsilon A}{d}$.Here, $A$ is the plate area and $d$ is the separation between plates.When the plate area $A$ increases, the capacitance $C$ increases proportionally.The voltage a capacitor can withstand is determined by the dielectric strength and plate separation, not by the plate area alone.Thus, increasing the plate area causes the capacitance to increase.Answer:D. The capacitance increases.
