The correct answer is D. Check the network logs for evidence of port flapping. Since the NIC, cable, and workstation configuration have all been ruled out, and the problem persists even with a known-good PC on the same switch port, this behavior points to an unstable link at the switch itself (often called “port flapping”).

Explanation
Since the NIC, cable, and workstation configuration have all been ruled out, and the problem persists even with a known-good PC on the same switch port, this behavior points to an unstable link at the switch itself (often called “port flapping”). Examining the switch’s event or syslog will reveal if the port is constantly going up and down, confirming a hardware or configuration issue on the switch side.
