Consider the following statements regarding water potential and osmosis: 1. Pure water has the highest possible water potential, which is defined as zero at standard temperature and pressure. 2. The addition of solutes increases the free energy of water, thereby increasing the water potential. 3. Water always moves from a region of higher water potential to a region of lower water potential. Which of the statements given above are correct?

Options:

• A: 1 and 3 only
• B: 1 and 2 only
• C: 2 and 3 only
• D: 1, 2 and 3
