To correctly determine the motion of the object over the specified intervals based on the graph (which I cannot see), let's define what each type of motion typically represents:
- **Constant speed**: The object travels equal distances in equal time intervals, represented by a straight, non-horizontal line on a distance-time graph.
- **Acceleration**: The object's speed is increasing over time, indicated by a curve upward on a distance-time graph.
- **Decreasing speed**: The object's speed is slowing down, typically shown by a curve downward on a distance-time graph.
- **No motion**: The object does not change its position over time, represented by a horizontal line on a distance-time graph at a constant distance.
With that understanding, evaluate each response based on the intervals listed (AB, BC, CD, DE) and how they might appear on a distance-time graph.
From the options provided, the most likely correct option, based on the descriptions of motion, would be the first option:
- **interval AB → constant speed**
- **interval BC → acceleration**
- **interval CD → constant speed**
- **interval DE → no motion**
However, without the actual graph to analyze the specific shape and features of the line (how it behaves across the time intervals), I can't definitively select the appropriate intervals and trends. You will need to visually identify the characteristics of the graph for each segment and compare them against the definitions provided above.
