When can a grayscale image be used?

Answer and explanation

Correct answer: When color information is unnecessary and brightness or intensity is sufficient

A grayscale image represents each pixel using a brightness or intensity value instead of separate color channels. It is suitable for tasks such as edge, shape, or pattern detection when color is not needed. Color information is necessary when objects must be distinguished by their colors.
