What is the function of a capacitor in a low-pass filter?

A. To block high-frequency signals and allow low-frequency signals to pass
B. To amplify low-frequency signals
C. To filter out low-frequency noise
D. To store energy for later use

Explanation:

In a low-pass filter, the capacitor blocks high-frequency signals and allows low-frequency signals to pass through, providing noise filtering.
