Concept:Uniform acceleration means displacement is proportional to the square of time when starting from rest.Explanation:For uniformly accelerated motion from rest, $s = \frac{1}{2}at^2$.This shows $s \propto t^2$, exactly as stated in the question.If displacement were proportional to time, the motion would have uniform velocity.Since it is proportional to $t^2$, the acceleration must be constant.Thus, the car is moving with uniform acceleration.Answer:A. Uniform acceleration
