Answer: C. The red blood cells released water through osmosis. The release of water helped the blood cells keep a similar concentration of solutes as the outside solution.

Explanation:

Osmosis is a process whereby water molecules move from an area where they are in higher concentration than a solute to an area where they are in lower concentration. They do this by moving through a selectively-permeable membrane.

With sugar added to the solution, the water in the red blood cells will have a higher concentration of water in the cells than the solution so water molecules will move from the cell - through the cell membrane - to the solution. They will keep doing so till the concentration of solutes are more or less similar in both the cells and the solution.
