C Correct answer
Explanation

A capacitor is an electronic component designed to store electric charge. It consists of two conductive plates separated by an insulating material (dielectric). When voltage is applied, charge accumulates on the plates, creating an electric field that stores energy. Capacitors are commonly used for filtering, energy storage, and timing circuits.
