Which bit rate is associated with monochrome images?

Monochrome images refer to images that contain only one color or shades of one color, typically black and white. The bit rate associated with these images determines the number of colors that can be represented in the image. A 1 bit rate is sufficient for monochrome images because it can represent two states: one for black and another for white.

In contrast, a bit rate of 2 bits would allow for four possible values (00, 01, 10, 11), which could represent black, white, and two shades of gray. However, for true monochrome, only two states are necessary. Higher bit rates, such as 8 bits or 24 bits, are used for color images and can produce a much broader spectrum of colors, far beyond what is needed for a simple black and white representation. Thus, the use of a 1 bit rate aligns perfectly with the characteristics of monochrome images, making it the correct choice.
