The figure represents a(n) ______.
A. angle
B. line segment
C. ray
D. line

Answer:
B. line segment
because without the point A it would be a ray
or without the arrow after point a it would be a line
The figure a(n) represents a line segment Option(B)
A line is a one-dimensional figure, which has length but no width. A line is made of a set of points which is extended in opposite directions infinitely. It is determined by two points in a two-dimensional plane.
In geometry, a ray is usually taken as a half-infinite line (also known as a half-line) with one of the two points and. taken to be at infinity.
A line segment is bounded by two distinct points on a line. A line has no endpoints and extends infinitely in both the direction but a line segment has two fixed or definite endpoints.
The given figure is a line segment as it has two end points a and b and also it is bounded by the similar two extended point .
Therefore a(n) is a line segment, Option (B.)
