Geometry

The correct answer is B. line segment.

Let's analyze each option based on the definitions of geometric terms:

A.A point is a location in space. It has no size, no length, no width, and no height. It is represented by a dot and is used as a fundamental building - block for other geometric figures. It is not a part of a line with two endpoints, so this option is incorrect.

B.A line segment is precisely defined as a part of a line that is bounded by two distinct endpoints. It has a definite length, which can be measured. For example, if we have two points and , the line segment is the set of all points between and including
