The best response that describes displacement is:
"Displacement is a vector quality showing total length of an area traveled by a particular object."
However, the statement is somewhat misleading because displacement refers to the change in position of an object and is defined as the straight line distance from the initial position to the final position in a specific direction, not the total length of the area traveled.
Therefore, the correct definition of displacement is that it is a vector quantity that considers both distance and direction from the initial to the final position, not total distance traveled. If this accurate description is not among the choices, you may want to recognize that the closest understanding involves displacement being a vector quantity.
