Explanation:

  • Statement A: A substance is said to be in the liquid state if under normal pressure its M. P. is below the room temperature. This statement is true. A substance is said to be in the liquid state if its melting point is below the room temperature. For example, water has a melting point of 0°C and boils at 100°C under normal pressure, which is why it is a liquid at room temperature.

  • Statement B: The melting point of solid and the freezing point of liquid is different. This statement is also true. The melting point of a solid and the freezing point of a liquid are different phenomena. The melting point is the temperature at which a solid turns into a liquid, while the freezing point is the temperature at which a liquid turns into a solid. The melting point and freezing point of a substance are the same, but they occur in opposite directions.


Therefore, the correct answer is option 'C' - Statement A.
