The correct answer is: A. moving the plates further apart.
A capacitor is a device that stores electrical energy in an electric field. It consists of two conductive plates separated by an insulator. The capacitance of a capacitor is the amount of charge that it can store for a given voltage. The capacitance of a capacitor can be increased by increasing the area of the plates, decreasing the distance between the plates, or using a material with a higher dielectric constant.
Option B is incorrect because moving the plates closer together will decrease the capacitance. This is because the electric field between the plates will be stronger when the plates are closer together, and the plates will be able to store less charge.
Option C is incorrect because increasing the voltage applied to the plates will not change the capacitance. This is because the capacitance is a property of the capacitor itself, and it is not affected by the voltage applied to the plates.
Option D is incorrect because decreasing the voltage applied to the plates will not change the capacitance. This is for the same reason that increasing the voltage applied to the plates does not change the capacitance.
Option E is incorrect because moving the plates further apart is the only option that will increase the capacitance.
