Solution
The correct option is C Hypertonic solution
Plant cells are surrounded by a dead cellulosic cell wall. The plant cell wall is fully permeable and cannot regulate the entry or exit of solutes or solvent. When a plant cell is present in a hypertonic solution plant cell will lose water through exosmosis. As the plant cell keeps on losing water, the protoplasm shrinks and moves away from the cell wall, the hypertonic solution moves inside the space between cell protoplasm and cell wall.
