None of the above

Detailed explanation-1: -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. In an isotonic solution, no net movement of water will take place.
Detailed explanation-2: -In an isotonic solution, the flow of water in and out of the cell is happening at the same rate. Figure 8.4.
Detailed explanation-3: -The main difference between hypotonic, isotonic and hypertonic solutions is that isotonic solutions are solutions having equal osmotic pressures, while hypotonic solutions are solutions having a lower osmotic pressure and hypertonic solutions are solutions with a high osmotic pressure.
