Why each option
The DE-15 (also called HD-15 or DB-15) is the 15-pin high-density D-sub connector used by VGA video interfaces.
SCSI interfaces use 50-pin, 68-pin, or 80-pin connectors depending on the variant - none of which match the DE-15 form factor.
Parallel printer ports use the DB-25 (25-pin) connector on the PC side and the Centronics 36-pin connector on the printer side, not DE-15.
RS-232 serial interfaces use the DE-9 (9-pin) or DB-25 (25-pin) D-sub connectors, not the 15-pin DE-15.
The DE-15 connector has 15 pins arranged in three rows within a D-shaped shell and is the standard connector for the VGA (Video Graphics Array) analog video interface. It carries separate red, green, blue, horizontal sync, and vertical sync signals to the display.
