Answer:

D: a Hypertonic sucrose solution

Explanation:

Sucrose cannot pass through the membrane and Hypertonic solution's cause cells to shrink.

Osmosis would cause red blood cells to shrink the most when immersed in a hypertonic sucrose solution.

What is osmosis?

  • The movement of solvent from a region of high water potential to a region of low water potential through a semi-permeable membrane is called osmosis.

What do you mean by hypertonic?

  • "Hypertonic means that the environment outside of the cell has a higher concentration of solutes than the cell itself."

If a red blood cell having 2% concentration of solutes(and 98% water) when put in a hypertonic solution( more concentration of solute than solvent), then the solvent from RBC (mostly water) flows out from the cell and causes it to shrink.

Hence, the answer is d. a hypertonic sucrose solution.
