The correct answer is B. 640 x 480.
The VGA (Video Graphics Array) standard was developed by IBM in 1987. It was the first video standard to support a resolution of 640 x 480 pixels. This resolution was chosen because it was a good compromise between the need for high resolution and the need for compatibility with existing hardware.
The VGA standard also defined a number of other features, including a palette of 256 colors, support for text and graphics, and a variety of video modes. The VGA standard was widely adopted and became the de facto standard for video displays in the late 1980s and early 1990s.
The VGA standard was eventually superseded by newer standards, such as SVGA (Super VGA) and XGA (Extended Graphics Array). However, the VGA standard remains popular today, as it is supported by a wide range of hardware and software.
The other options are incorrect because they do not represent the native resolution of a VGA display.
