Which component helps preserve date and time even when the computer is switched off?

Answer and explanation

Correct answer: CMOS Battery

The CMOS battery supplies a small, continuous amount of power to the real-time clock and CMOS settings on the motherboard when the computer is switched off. This is why the system can remember the date, time, and some basic hardware settings. Main memory loses its contents without power, while a fan and speaker do not store clock information. Therefore, option C is correct.
