Solution

B. area of the plate is increased

Explanation

The Area of the Plates Increases: The capacitance is directly proportional to the surface area of the capacitor plates. If you increase the area of the plates, the capacitance will increase.

The Distance Between the Plates Decreases: The capacitance is inversely proportional to the distance between the capacitor plates. If you decrease the separation between the plates, the electric field between them increases, resulting in an increase in capacitance.

The formula for the capacitance (C) of a parallel plate capacitor is given by:

C=dε⋅A​

where:

$\mathrm{�}$

• C is the capacitance, 
• ε is the permittivity of the material between the plates, 
• A is the area of the plates, and 
• d is the separation distance between the plates.

Therefore, increasing the area of the plates or decreasing the distance between the plates will result in an increase in capacitance.
