terpreting Position vs Time Graphs

A graph titled Position versus time for with horizontal axis time (seconds) and vertical axis position (meters). The line runs in 3 straight segments from 0 seconds 0 meters to 4 seconds 12 meters to 6 seconds 12 meters to 12 seconds 0 meters.
Based on the graph, describe what is happening between 4 and 6 seconds.

The object is moving away from the start at a constant speed.
The object is not moving.
The object is returning to the start at a constant speed.
The object is changing speed.

Between 4 and 6 seconds, the graph shows a horizontal line at the position of 12 meters. This indicates that the position of the object remains constant during this time interval, meaning the object is not changing its position. Therefore, the correct interpretation is:

The object is not moving.
