A GIF image that has only web-safe colors has a) Exactly 216 colors b) Exactly 256 colors c) No more than 216 colors d) No more than 256 colors e) No more than 16.7 million colors if the A is the correct answer, why c is not correct because any image may have colors less than 216, in other words may an image contain 100 colors or 105 colors etc.., so it depends on the image itself. Therefore, the best answer is c) no more than 216 colors.

please justify why c) No more than 216 colors is not the correct answer.
