In a distance-time graph, if the slope is curved towards the vertical (upwards) it is ...

Explanation:
The key idea is that on a distance–time graph, the slope represents velocity—the steeper the slope, the faster you’re moving. If the slope becomes steeper as time goes on (curving toward the vertical), the velocity is increasing with time, which means the object is accelerating. That’s why accelerating is the best answer. If the slope were to become less steep as time passes, it would be slowing down (decelerating). A straight line with a constant slope shows constant speed. A horizontal line, where distance doesn’t change, would mean the object is stopped.
