Multiple Choice

An analog interface used for connecting video display devices.

Explanation:
VGA is the analog video interface. It transmits video as continuous electrical voltages for red, green, blue, plus synchronization signals, using a 15-pin D-sub connector. Because the signal is analog, it can degrade with cable length and interference and it’s a technology that predates modern digital standards. The other options are digital interfaces (HDMI and DisplayPort) or typically digital in their common forms (DVI-D), with only some DVI variants carrying analog signals. So, among these, VGA is the analog choice used to connect video display devices.
