Selected Answer: B
Explanation: 12V Power Connector: High-end workstation PCs often have a 12V power connector (usually a 4-pin or 8-pin connector) that provides additional power to the CPU. If this connection is not made, the system may fail to POST and power off shortly after turning on. Symptoms of Missing 12V Connection: The fact that the PC turns on for a few seconds and then shuts down suggests that the CPU is not receiving sufficient power, which is often linked to the 12V connector being disconnected.
