Solution

The correct option is C acceleration is constant
If the displacement of a body varies as the square of elapsed time, then its acceleration is constant,
i.e $s = \frac{1}{2} a t^{2}$ .

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.
