Using conservation of momentum:

$\begin{gathered} m1v1+m2v2=0 \\ _{\text{ }}Where\colon \\ m1=35\operatorname{kg} \\ m2=11\operatorname{kg} \\ v1=_{\text{ }}speed_{\text{ }}of_{\text{ }}the_{\text{ }}kid \\ v2=_{\text{ }}speed_{\text{ }}of_{\text{ }}the_{\text{ }}ball \\ so\colon \\ v1=-(11)/(35)v2 \\ _{\text{ }}where\colon \\ (11)/(35)<1 \\ so\colon \\ v2>v1 \end{gathered}$

We can conclude that the answer is:

C. The kid will move to the left at a lower speed than the ball moves to the right.
