What can be inferred about the osmosis of water in potato cells?

A. The cells stop gaining water by osmosis in the 0.2M solution, so the concentration of glucose in the potato cells must be greater than 0.2M.
B. The cells stop gaining water by osmosis in the 0.2M solution, so the concentration of glucose in the potato cells must be between 0.1M and 0.2M.
C. In the solutions where the cells lose water by osmosis, the original concentration of water in those cells must be less than the concentration of water in the solutions.
D. In the solutions where the cells gain water by osmosis, the original concentration of water in those cells must be greater than the concentration of water in the solutions.
