Answer: C. RJ45
100BaseT, also known as “fast internet”, is a network standard used to achieve very fast data transfer rates of up to 1000 Mbps. Generally, 100BaseT is known to be 10 times faster than the standard Ethernet. High speed computer network applications are supported by RJ45 connectors. Although not the fastest Ethernet cable, the RJ45 connector has become the most common type of socket design in networking today.
