B

C
refers to the number of colors per pixel that can be displayed in an image and affects image quality and file size
D
images composed of grids of pixels that have a fixed resolution and cannot be resized without losing image quality
Explanation: 

Detailed explanation-1: -Color depth is also known as bit-depth which refers to the number of bits used to define the color channels, red, green or blue, for each pixel. In most RGB systems, there are 256 shades per color channel. If you know binary system well enough, this number 256 should sound very familiar to you.

Detailed explanation-2: -The number of bits determines the range of colours. This is known as an image’s colour depth . For example, using a colour depth of two, ie two bits per pixel, would allow four possible colours, such as: 00-black.

Detailed explanation-3: -The higher the color depth, the better your images will generally look on the screen. Images viewed at the 16-colors setting will usually look less refined than the same images viewed at the 256-colors setting because there are not as many colors to display tones and variations.
