Velocity of the particle must be zero at an instant.

Vedclass · Answer

(B) The average velocity is defined as $	ext{Average Velocity} = \frac{	ext{Total Displacement}}{	ext{Total Time}}$.If the average velocity is $0$,then the total displacement must be $0$.For a particle moving in a straight line to have a displacement of $0$,it must return to its starting position.To return to the starting position,the particle must change its direction of motion at some point.At the instant the particle changes its direction,its velocity must be $0$ (assuming continuous motion).Therefore,the velocity of the particle must be zero at at least one instant in the interval.

If the average velocity of a particle moving on a straight line is zero in a time interval,then:
