Answer:
C. 3
Explanation:
A histogram illustrates the frequency of occurrence of each pixel value in a picture by providing a graphical representation of the distribution of pixel values. Every pixel in an RGB image contains three color values—one for each of the image's color channels, each of which has its own histogram. The distribution of red color values in the image is displayed by the red histogram, that of green color values by the green histogram, and that of blue color values by the blue histogram.
