Final Answer :
D
Explanation :
A loopback plug is a device that loops the transmit signal from the network interface card (NIC) back to its receive signal. This allows the technician to test the NIC without the need for network connectivity or another device on the other end of the cable. A cable tester, multimeter, or cable certifier can be used to troubleshoot network cables but may not be as effective in diagnosing issues with the NIC itself.
