Displacement is the vector quantity among the options provided.
- Distance is a scalar quantity that refers to how much ground an object has covered during its motion, regardless of its starting or ending point.
- Time is also a scalar quantity, measuring the duration of an event.
- Speed is a scalar quantity that measures how fast an object is moving, regardless of its direction.
In contrast, displacement is a vector quantity because it describes the change in position of an object and includes both the magnitude and the direction of that change.
