How many pins are on a VGA connector?

A VGA (Video Graphics Array) connector is designed to provide a standard interface for video output from computers to monitors. It has a total of 15 pins arranged in three rows of five pins each. This design allows the VGA connector to carry video signals, typically in an analog format. The 15 pins are used to transmit various color signals (red, green, blue) as well as horizontal and vertical sync signals, among others, facilitating the connection of the computer's graphics output to the display.

The other options provided do not accurately reflect the configuration of a VGA connector. Specifically, while 9 pins and 25 pins are used in different connector types or historical standards, only a 15-pin configuration aligns with the specifications for VGA connectors. The 37-pin option also does not correspond to VGA or any common video output connection type in typical computer setups.
