The cell membrane has selective permeability and chooses which to pass through. Non polar molecules can pass easily with diffusion, but ions cannot.
I think the correct answer would be C. It would be restricting water and/or nutrients, instead of supplying ample quantities of both that would not change the results of the experiment. This is because you are still supplying the same amount of nutrients and other things needed by the plant so the ratio of the growth of the plants will still be the same.
