Which of the following is a fragment?

a. The dancer floated across the stage.

b. The rams locked horns, and the tourists watched them from far away.

c. The canoe with the blue stripes.

d. The truth can be unpleasant.

C. the canoe with the blue stripes.

This would be the fragment because it needs to be part of an other sentence that describes what the canoe is doing to have meaning. The fragment "the canoe with the blue stripe" has no meaning on its own

The correct answer is C. The canoe with the blue stripes. This is a fragment because it does not convey meaning on its own and has to have another part of the sentence, usually a predicate that would describe what the canoe was doing. Other sentences can stand on their own and convey meaning and do not need any more additions.
