Answer: Option (C) is the correct answer.
Explanation:
In the given reaction it is shown that there occurs a change in state of water molecule from solid to liquid state.
When ice melts then basically heat is absorbed by it due to which its molecules gain kinetic energy. As a result, the atoms of water start to move from their initial position.
Hence, they collide rapidly with each other leading to change in state of ice from solid to liquid.
Therefore, we can conclude that it requires energy to melt ice and turn it into water would be the best argument against writing this in the form a chemical equation like this.
