Find the correct one.

1. All the solutions have lower water potential than pure water given that solution is under external pressure.

2. All the solutions have lower water potential than pure water.

3. All the solutions have higher water potential than pure water.

4. All the solutions have lower water potential than pure water unless the solution is under such external pressure which is more than the solute potential.
