(C) The velocity of the body is given by $v = 20 + 0.1t^2$.Acceleration $a$ is defined as the rate of change of velocity with respect to time,$a = \frac{dv}{dt}$.$a = \frac{d}{dt}(20 + 0.1t^2) = 0 + 0.1 \times 2t = 0.2t$.Since the acceleration $a = 0.2t$ depends on time $t$,it is not constant.Therefore,the body is undergoing non-uniform acceleration.
