You are heating crushed ice and a small amount of water and monitoring the temperature of the icy slurry until it reaches the point were the ice is nearly melted. How does the temperature change during this process?

The temperature stays at exactly 100°C.
The temperature stays at constant throughout.<<<<>
The temperature goes up sharply as you heat the icy water.
