Which option properly describes the pinouts for the T-568A end of a crossover network cable?

The correct description of the pinouts for the T-568A end of a crossover network cable is based on how the wiring is configured to connect devices directly to each other. In a crossover cable, specific pairs are crossed over to facilitate communication between devices, typically two computers or switches, without the need for a hub or switch.

The T-568A standard is defined by its pinout configuration, where pairs are assigned specific pins for both ends of a cable. The correct pinout for the T-568A configuration is established as follows: the first pair uses pins 1 (white/green) and 2 (green), the second pair uses pins 3 (white/orange) and 6 (orange), and the third pair uses pins 4 (white/blue) and 5 (blue), with the fourth pair using pins 7 (white/brown) and 8 (brown).

In this context, option A lists the pinouts in the correct configuration for a crossover cable using the T-568A standard, specifically placing the transmit and receive pairs in the proper positions to enable communication. The pairing required for crossover cables involves connecting the transmit pin on one end to the receive pin on the other and vice versa; hence
