Which cable carries video signal only?

• A. RCA Cable
• B. HDMI Cable
• C. BNC Cable
• D. XLR Cable

Answer: (C)

Video cables are chosen for what they’re designed to carry and how cleanly they can transmit that signal. The cable with the BNC connector is the one most closely associated with carrying a video signal by itself in professional setups. It uses a coaxial design with the right impedance to minimize loss and interference, and its locking connector helps keep the signal steady on cameras, monitors, and broadcast gear. This makes it a dedicated path for video in many workflow environments.

RCA cables can carry video, but they’re part of a broader family that often includes audio paths as well, and the yellow video channel isn’t exclusively for video-only use in typical setups. HDMI carries both video and audio along with other data, so it isn’t video-only. XLR cables are designed for balanced audio signals, not video.
