Which of the following constitutes the main internal tissue of a leaf?

Four cells with osmotic potential equivalent to that of 3% salt solution were immersed respectively in solutions
of different concentrations labeled as follows: I = 4% salt solution; II = 6% salt solution III = 1% salt solution;
IV = 10% salt solution; V = 5% salt solution. Which of the solutions will cause an increase in osmotic
pressure within the cell?
