Explanation:

The problem describes that the mass of the substance (ice - water - steam) remains 100g throughout the phase changes. The law of conservation of mass states that mass is neither created nor destroyed in a chemical or physical change. Option a is incorrect as it's not about conserving ice specifically. Option b is incorrect as it's not about conserving water in the form but about the mass. Option c, conservation of mass, fits as the mass remains constant during the phase transitions.

Answer:

c. conservation of mass
