Answer: A) Line Segment

Step-by-step explanation:

Hi, a line segment is a part of a line between two points. It has definite endpoints (segment), and those points are also included in the line.

A ray only has one endpoint,  

Point is not a length.

Since Sidney describes the ruler as a length of plastic that starts at 0 and continues on to 12 inches, she is using the line segment geometric term.
