Final Answer :
B
Explanation :
A loopback plug is commonly used to test a particular port, such as a network or serial port. It can help verify that the port is functioning properly by sending data in and receiving the same data back out, essentially creating a loopback. It would not be used for testing other components such as the motherboard, power supply, or hard drive.
