The correct answer is:

A. pixels.

Raster images, such as those created by digital cameras, scanners, and other imaging devices, are made up of a grid of tiny individual dots called pixels.

Pixels are the basic building blocks of raster images, and each pixel represents a specific color or shade of gray. The more pixels an image has, the higher its resolution and the greater the level of detail it can convey.

In contrast, vector images are made up of mathematical descriptions of shapes, lines, and curves, rather than a grid of pixels. Vector images can be scaled to any size without losing quality.

JPEG and GIF are file formats used to store and compress raster image data, but they are not the fundamental building blocks of raster images themselves. Pixels are the fundamental elements that make up raster images.

Therefore, the correct answer to the question "Raster images are made up of tiny dots called:" is A. pixels.
