To answer this question, we need to understand the concept of color depth in monitors.
Color depth refers to the number of distinct colors that can be represented on a display. It is measured in bits, and each bit represents a binary value (0 or 1).
A 24-bit monitor is capable of displaying 24 bits per pixel. Since each bit can have two possible values (0 or 1), a 24-bit monitor can represent 2^24 different combinations of bits.
Therefore, a 24-bit monitor is capable of displaying 2^24 = 16,777,216 different colors.
The correct answer is C) 17,000,000. This option is correct because a higher-end 24-bit monitor is capable of displaying approximately 16.8 million colors.
