Detailed explanation-1: -Final answer: Space between the cell wall and plasma membrane in a plasmolysed cell is filled with hypertonic solution.

Detailed explanation-2: -Now, as the cell wall is freely permeable, it will allow everything inside it and hence in the space between the cell wall and plasma membrane, there will be a hypertonic solution present. So, the correct option is ‘Hypertonic solution’.

Detailed explanation-3: -A cell placed into a hypertonic solution will shrivel and die by a process known as plasmolysis. An isotonic solution is any external solution that has the same solute concentration and water concentration compared to body fluids.

Detailed explanation-4: -As a result, the hypertonic solution will occupy the space between the plasma membrane and the cell wall. Thus the correct answer is option C.

Detailed explanation-5: -Thus, the space between the cell wall and condensed protoplast is filled with hypertonic solution in a plasmolyzed cell.
