c.water heats.
d.water vapour condenses.

Answer 1

heat is liberated when ice melts.

I hope it will help you.

Answer 2

Heat is liberated when ice melts, so option B) ice melts is the right answer.

The reason why the heat gets liberated is the ice will be usually found in the solid state, and when it starts to melt, slowly it turns into the liquid state.

At that point, heat energy will be released into the air completely.

At the time of melting, ice will get enough energy to break.

Hope this helps.
