Final Answer : C, Explanation :  A solution with a lower concentration of solutes (0.5% saline) compared to the cell's internal environment (0.9% saline, which is isotonic) is hypotonic. This causes water to move into the cell, potentially leading to swelling, not shrinking or crenation.

A) is hypertonic to the cell.
B) will cause crenation of the cell.
