Which resolution represents the lowest quality in the Axis naming convention structure?

In the Axis naming convention for video resolution, VGA stands for Video Graphics Array, which has a resolution of 640x480 pixels. This resolution is considered standard definition (SD) and is the lowest quality among the options provided.

The other resolutions listed are significantly higher in terms of pixel count and clarity. For instance, 720P (1280x720) is recognized as high definition (HD) and offers better image quality than VGA. Similarly, 3/4MP (2560x1440) and 5MP (2592x1944) are both classified as higher definitions, with a much greater number of pixels, providing increased detail and sharpness in images.

Therefore, VGA, being the least pixel-dense option, clearly represents the lowest quality within this selection.
