Solution

The correct option is C II and IV are correct.
Speed is a scalar quantity while velocity is a vector quantity.
An object can have constant speed but velocity will change since velocity is a vector quantity.
Without having a varying speed non-zero acceleration. Uniform circular motion is an example of options B and D
Thus, B and D options are correct

Explain your answer.

Mark the correct statement(s)
(1) If speed of a body is varying, its velocity must be varying and it must have non-zero acceleration.

(2) If velocity of a body is varying, its speed must be varying.

(3) A body moving with varying velocity may have constant speed.

(4) A body moving with varying speed may have constant velocity, if its direction of motion remains constant.
