Answer: A
Explanation:
Video connections use many of the same connectors as analog and digital audio. Pro video applications generally use XLR or BNC cables, whereas consumer video equipment often uses RCA phono plugs.

Specialized video connectors include S-Video (also called Y/C) connections, which are transmitted on 4-pin mini-DIN connectors to provide greater color depth than composite video. There are also unique connectors for new high-definition digital video formats like HDI and DVI.
