Why each option
VGA uses the DB-15 (also called HD-15) connector - a 15-pin D-shaped plug arranged in three rows that carries analog RGB video signals.
S-video uses a round 4-pin or 7-pin mini-DIN connector to carry separate luma and chroma signals, not a DB-15.
DVI-A uses the DVI connector form factor with a specific analog pin layout, which is physically and electrically distinct from the DB-15.
DVI-D uses the DVI connector form factor for digital-only signal transmission and does not use a DB-15.
The VGA (Video Graphics Array) interface is defined by its DB-15 connector, which has 15 pins in three rows of five, transmitting analog red, green, blue, horizontal sync, and vertical sync signals to a display.
