What is the common standard resolution for a VGA display?

The common standard resolution for a VGA (Video Graphics Array) display is 640x480. This resolution is often referred to as VGA resolution and is one of the earliest display standards, which originated in 1987. VGA supports various resolutions, but 640x480 is its base resolution, establishing a legacy for subsequent display technology.

The other choices represent different resolutions that may be used in various contexts: 800x600 is commonly known as SVGA (Super VGA), 1024x768 is XGA (Extended Graphics Array), and 1920x1080 is known as Full HD or 1080p, which was developed much later. None of these resolutions are considered standard VGA, making 640x480 the correct context for the VGA display.
