Consider a container with a semipermeable membrane dividing

Consider a container with a semipermeable membrane dividing the volume. If the volume on the right has a water potential of -0.7 MPa. Which of the following water potential values in the left side will cause water to move to the left in the largest quantities?

This is all the info given for this question. There is no more info to find the correct answer.

Solution

Ans.

As we know that pure water potential is 0 and impure water is less than 0 so option A is excluded.

As we know that water moves from higher water potential to lower water potential so all the options other than A are correct.
