the ice removed heat from the ice cream mix causing it to freeze.
the ice added heat to be ice cream mix causing it to be solid.
the ice added heat to the ice cream mix causing it to be liquid.

Explanation:

When ice is added around the container, it absorbs heat (removes heat) from the ice - cream mix. When a liquid loses heat, it can change its state from liquid to solid (freeze). Melting occurs when a solid gains heat (not the case here as the ice - cream went from liquid to solid). Adding heat would not cause a liquid to become solid (eliminates options where heat is added).

Answer:

The ice removed heat from the ice cream mix causing it to freeze.
