Correct Answer:
D. Displacement
In physics, the Displacement is defined as the shortest straight-line distance between an object's initial and final positions, including the direction. It is a vector quantity. Distance (A) refers to the total path length traveled, which can be longer than the displacement if the path is not straight. Speed (B) is a scalar quantity that measures how fast an object is moving, while Velocity (C) is a vector quantity that measures the rate of change of displacement, including direction. Neither speed nor velocity represents the minimum distance between two points.
