Question

which one is a line segment?

Explanation:

A line - segment has two endpoints. Based on the visual representation of the options, we need to identify the one with two distinct endpoints.

Answer:

(Without seeing the actual visual content of options a, b, c, d, we can't give a specific answer. But if we assume standard geometric figures, a line - segment is a straight path between two points. If one of the options shows a straight figure with two endpoints, that would be the correct one.)
