Final answer:

To create an RJ45 loopback plug, connect pin 1 to pin 3 and pin 2 to pin 6 to return transmitted signals back to the receiving pins, which is effective for network testing.

Therefore, the correct answer is: option e. connect pin 1 to pin 3 and pin 2 to pin 6.

Step-by-step explanation:

A loopback cable is also known as loopback plug or loopback adapter, which is a plug used to test physical ports to identify network issue.

To create a loopback plug with a single RJ45 connector, you should connect the wires in the connector in such a way that sends signals out from one pin and directly back into another pin.

The correct way to wire a loopback plug is option : connect pin 1 to pin 3 and pin 2 to pin 6. This is because Ethernet uses pins 1 and 2 for transmitting data and pins 3 and 6 for receiving data.

By connecting pin 1 to pin 3 and pin 2 to pin 6, you are directly returning the transmitted signals back to the receiving pins, creating a loop that can be used for testing purposes.
