If two devices simultaneously transmit data on an Ethernet network and a collision occurs, what does each station do in an attempt to resend the data and avoid another collision?

Question $6$ options:

Each device compares the other device's priority value $($determined by IP address$)$ with its own, and the device with the highest priority value transmits first.

Each device waits for a clear$-$to$-$send $($CTS$)$ signal from the switch.

Each device randomly picks a priority value, and the device with the highest value transmits first.

Each device sets a random back$-$off timer, and the device will attempt retransmission after the timer expires.
