Answer:
C shrink
Explanation:
 a hypertonic solution has more solutes than the intracellular environment, so water will leave the cell to try to achieve equilibrium. If enough water is lost, the cell will take on a wrinkled or shriveled appearance. In red blood cells this is called crenation and the surface of the cells take on a scalloped appearance. A high amount of water loss can be damaging or even fatal for a cell.
