(B) In a displacement $(X)$ versus time $(t)$ graph,the slope represents the velocity of the particle. For a graph to be physically possible,a particle must have only one unique position at any given instant of time $(t)$.Option $(A)$ is possible as it represents a particle moving away and then returning.Option $(C)$ is possible as it shows motion in both directions.Option $(D)$ is possible as it represents a particle moving with constant velocity,resetting,and repeating.Option $(B)$ is not possible because at a specific instant of time $(t)$,the graph shows two different values of displacement $(X)$. Since a particle cannot be at two places at the same time,this graph is physically impossible.

Which of the following displacement $(X)$ time graphs is not possible?
