The answer should be B. 复位键开关. The option D in your question contains incorrect information.

RESET SW stands for "Reset Switch," which is the physical connection for the reset button on a computer case. When pressed, it sends a signal to the motherboard to restart the system, similar to using the software restart function but at the hardware level.

Other options analysis:

A (速度指示灯) and D (电源指示灯) typically connect to pins labeled HDD LED (hard drive activity) and PWR LED (power status), respectively.

C (电源开关) connects to the PWR SW pin, responsible for turning the system on/off.

Always refer to your motherboard manual for precise pin layouts, as configurations may vary between manufacturers. Have you encountered issues with front panel connections, or were you simply clarifying component functions?
