Choose the correct statement(s) :
(A) If a particle moving in a straight line has a negative acceleration then this always meant that the speed is decreasing.
(B) If speed of a particle moving in straight line changes, it must have non-zero acceleration.
(C) Acceleration of a particle is negative if it is moving in \( +v e \) direction with decreasing speed.
(D) Rate of change of speed is magnitude of acceleration at any instant.
