Answer: A - Jack should use the crossover cable to connect the two computers (peers) with each other.

Key Takeaway: Crossover cables are very similar to straight-through cables, except that the transmit and receive wires in each pair of wires are reversed from end to end. This allows each device to receive data on each wire on which the other device is sending data. This, in turn, allows two devices to communicate via Ethernet directly without the need of an intervening switch.
