None of the above

Detailed explanation-1: -When a cell is placed in a hypertonic medium, it loses water due to the process of exosmosis. Exosmotic loss of water results in plasmolysis. Thus, the correct answer is option B.
Detailed explanation-2: -A hypertonic solution has increased solute, and a net movement of water outside causing the cell to shrink.
Detailed explanation-3: -A hypotonic solution causes a cell to swell, whereas a hypertonic solution causes a cell to shrink.
Detailed explanation-4: -On the other extreme, a red blood cell that is hypotonic (lower concentration outside the cell) will result in more water flowing into the cell than out. This results in swelling of the cell and potential hemolysis (bursting) of the cell.
Detailed explanation-5: -Hypertonic solutions cause blood cells to shrivel. Hypotonic solutions can cause the blood cell to burst from the pressure. There are three types of solutions that can occur in your body based on solute concentration: isotonic, hypotonic, and hypertonic.
