Which of the following cable types delivers a signal over a single pin connector?
The correct answer is B. Coaxial. Coaxial cable uses a single center conductor (pin) to carry the signal, surrounded by insulation, a metallic shield, and an outer jacket. The connector (e.g., BNC or F-type) connects via this single center pin. Ethernet (RJ-45) uses 8 pins. S-Video uses a multi-pin connector…

Explanation
Coaxial cable uses a single center conductor (pin) to carry the signal, surrounded by insulation, a metallic shield, and an outer jacket. The connector (e.g., BNC or F-type) connects via this single center pin. Ethernet (RJ-45) uses 8 pins. S-Video uses a multi-pin connector (typically 4 or 7 pins) to carry separate luma and chroma signals. DVI connectors use a large array of pins (up to 29) to carry digital and/or analog video signals. Coaxial is therefore the only cable in the list that delivers its signal through a single-pin connector.
