When working with images it is important to understand the different extension types which describes bitmant raster?

The question above does not have multiple choices. However, the best answer to this question is;

Raster or bitmap images are pixels represented in a rectangular grid and have a fixed resolution that cannot be resized. Reason behind this analogy in very simple terms is that each pixel is a “bit” of color information displayed on a screen. They are more common in general formats such as gif, jpg, png, and are heavily used on the web.

well cos like a ds it doesn't really die out, unlike for example, fifa, they always come out with a new version, so lets say your fifa 18 is charging you to update the teams and stuff, so, if messi were to go to real madrid (never gonna happen) it would switch messi to the other team, until the owners of fifa come out with fifa 19, then the game would eventually stop updating, and back to the ds, it doesn't really stop working after sometime because there's lots of things that it could be used for, and idk if u know what i'm saying, but long story short, samsung, represents the ds, if they still work, and people love them but not the new version, the old version still works, so they don't really force people to buy new phones, get me?

the answer is d underlined.
