Geometry

The name of this figure is D..

 

1. Analyze each option based on geometric definitions:

A.: This is a ray. A ray has one endpoint (point here) and extends infinitely in one direction (towards ). But the given figure extends infinitely in both directions, so it's not a ray.

 

B.: This is a line - segment. A line - segment has two definite endpoints ( and ). Since the figure in question has no endpoints and extends infinitely, it's not a line - segment.

 

C.: This is also a ray with endpoint extending towards . It doesn't match the figure that extends in both directions.

 

D.
