Why each option

The standard VGA connector uses a DB-15 (also called HD-15 or DE-15) form factor, a 15-pin D-sub connector arranged in three rows.

ADB-15Correct

VGA uses a DB-15 connector, which is a high-density 15-pin D-subminiature connector arranged in three rows of five pins. This connector carries analog video signals (red, green, blue) along with horizontal and vertical sync signals. It has been the standard analog video interface on PCs for decades.

BDB-9

DB-9 is a 9-pin D-sub connector used for legacy RS-232 serial ports, not VGA video output.

CDIN-6

DIN-6 is a round 6-pin connector historically used for PS/2 keyboards and mice, not video.

DDB-25

DB-25 is a 25-pin D-sub connector used for legacy parallel printer ports and some serial interfaces, not VGA.
