Answer

We can check the motion of the objects $C$ and $D$ by plotting the distance-time graph for the two objects.

Graph the object C on $x-$axis
Scale $1cm = 15$ min and on y-axis $1cm = 10m$
Since, the distance-time graph of the object $C$ is a straight line. Therefore, its motion is uniform.
Graph of object $D$
Scale On $x-$axis, $1cm = 15$ min, On $y-$axis $1cm = 5m$

Since, the distance-time graph of the object D is not a straight line, therefore, its motion is non-uniform.
