What does a resolution of 4:3 ratio signify?

1920 x 1200 resolution
1600 x 1200 resolution
1280 x 1024 resolution
1024 x 768 resolution

The correct answer is: 1600 x 1200 resolution

A resolution of 43 ratio signifies a screen resolution with a width that is 4 units long for every 3 units of height. This ratio is commonly associated with older TV and computer monitor resolutions and is considered "standard" for non-high definition displays. Option A, 1920 x 1200 resolution, has a 16:10 ratio and is typically used for widescreen displays. Option C, 1280 x 1024 resolution, has a 5:4 ratio and is commonly used for square-shaped monitors. Option D, 1024 x 768 resolution, has a 4:3 ratio but is typically considered a lower resolution than option B, making option B the correct answer.
