To answer this question, you need to understand how software programs define color. Let's go through each option to understand why it is correct or incorrect:

Option A) True - This option is correct because software programs, including web browsers, use a mathematical approach to define color. Colors in digital devices are represented using numerical values for red, green, and blue (RGB) channels. These values are then used in mathematical formulas to determine the final color displayed on the screen.

Option B) False - This option is incorrect because software programs do use a mathematical approach to define color.

The correct answer is A) True. This option is correct because software programs, including web browsers, use a mathematical approach to define color.
