a piece of a line with two endpoints
all points equidistant from a given point
two line segments with a common endpoint

Explanation:

• A ray has one endpoint and extends infinitely in one direction.
• Option A describes a line segment (two endpoints).
• Option B describes a circle (all points equidistant from a center point).
• Option C describes an angle (two line segments with a common endpoint).
• Only option D matches the definition of a ray.
