The correct answer is A. Crossover. This is a Crossover cable (A). In Ethernet wiring standards, T568B begins with orange-white and T568A begins with green-white. A crossover cable has one end wired to T568A and the other to T568B, causing the transmit pairs on one end to connect to the receive pairs on the…

Explanation
This is a Crossover cable (A). In Ethernet wiring standards, T568B begins with orange-white and T568A begins with green-white. A crossover cable has one end wired to T568A and the other to T568B, causing the transmit pairs on one end to connect to the receive pairs on the other. The differing wire color order between the two ends is the telltale sign of a crossover cable. A straight-through cable (C) would have identical pin-out on both ends. The cable has RJ-45 connectors, ruling out Fiber (B) and Coaxial (D).
