Answer: C) No, it extends infinitely in opposite directions.
The arrows indicate this. Since both sides go forever in those directions, this means we have a line instead of a segment. We can call this "line CD" or "line DC".
If you had only one side go on forever, then you'd have a ray. A segment is where it has two endpoints, and neither side goes on forever in that same direction. This means a segment has a finite fixed length; while the ray and line do not have a finite length.
