#### Answer

Choice C. We need to know the initial temperatures of the ice and of the liquid water.

#### Work Step by Step

If the ice and water were both initially at $0^{\circ}C$, the ice wouldn’t melt, because the system would be in thermal equilibrium and no heat would transfer. On the other hand, if the ice were at $0^{\circ}C$ but the water started out hot, at $100^{\circ}C$, the ice would all melt. More information is needed to answer the original question.
