$ \Delta E = W \neq 0, \ Q = 0 $

(C) According to the first law of thermodynamics,$\Delta E = Q + W$. Since the container is insulated,there is no exchange of heat with the surroundings,so $Q = 0$. Work is done on the system by the paddle,so $W \neq 0$. Therefore,the change in internal energy is equal to the work done,$\Delta E = W \neq 0$.
