Mark the correct statements :
(A) The magnitude of the instantaneous velocity of a particle is equal to its instantaneous speed.
(B) The magnitude of average velocity in an interval is equal to its average speed in that interval.
(C) It is possible to have a situation in which the speed of a particle is always zero but the average speed is not zero.
(D) It is possible to have a situation in which the speed of a particle is never zero but the average speed in an interval is zero.
