Detailed explanation-1: -Since all three components must be equal for any shade of gray there are only 256 possible combinations. Thus, grayscale images have a maximum color depth of 8 bits.
Detailed explanation-2: -An 8 bit grayscale image has 256 tonal options (2 to the 8th power) compared with the 2 tonal options of a 1 bit bitonal image. The tones of a grayscale image with a bit depth of 8 ranges from 0 (black) to 255 (white) and all the 254 shades of gray in between. depths ranging from 8 to 24 bits per pixel or higher.
Detailed explanation-3: -The number, 256, is 2 raised to the 8th power or the 8-bit color depth. This means that each of the RGB channels has 256 shades so there are 256x256x256 or 16, 777, 216 colors in total in this 8-bit RGB system. An 8-bit color system is capable of producing over 16 million colors.
Detailed explanation-4: -A grayscale image is composed of pixels represented by multiple bits of information, typically ranging from 2 to 8 bits or more.
Detailed explanation-5: -Option A is correct, Explanation-Grey scale images have a maximum color depth of 8bit.
