Question
Assertion : The molecules at $0^{\circ} \mathrm{C}$ ice and $0^{\circ} \mathrm{C}$ water will have same potential energy.
Reason : Potential energy depends only on temperature of the system.

Answer

(d) The potential energy of water molecules is more. The heat given to melt the ice at $0^{\circ} \mathrm{C}$ is used up in increasing the potential energy of water molecules formed at $0^{\circ} C$.
