Consider the following statements regarding the triple point of water: 1. It is the unique temperature and pressure at which the solid, liquid, and vapor phases of pure water coexist in stable thermodynamic equilibrium. 2. The temperature of the triple point of water is exactly 273.16 K (0.01 degrees Celsius). 3. It serves as a fundamental reference point for defining the Kelvin temperature scale. Which of the statements given above are correct?

Options:

• A: 1 and 2 only
