Explanation
VGA (Video Graphics Array) is an analog video interface that was the standard for monitors and projectors for many years. Older projectors commonly feature only a VGA (DB-15) port for video input. VGA carries an analog signal, matching the requirement stated in the question. HDMI and DisplayPort are digital interfaces and would not be compatible with an analog-only projector port without an active converter. RS-232 is a serial communication standard used for data transmission between devices (like configuring network equipment), not for video output.
