yKpoI14uk [10]

Answer:

The correct answer is option a. "the cells will shrink due to water loss by the cell".

Explanation:

Cells placed in a hypertonic solution will shrink due to water loss by the cell. An hypertonic solution has a high content of solutes dissolved, which makes it a solution with high tonicity. Water tends to move from a solution of low tonicity to a solution with high tonicity. As a result, cells placed in a hypertonic solution will start to loss their inner water and shrink, which causes its death.
