The solutions in the two arms of this U-tube are separated by a membrane that is permeable to water and glucose but not to sucrose. Side A is half-filled with a solution of 2 M sucrose and 1 M glucose. Side B is half-filled with 1 M sucrose and 2 M glucose. Initially, the liquid levels on both sides are equal. In the U-tube illustrated above, ________.
A) side A is hypertonic to side B
B) side A is hypotonic to side B
C) side A is isotonic to side B
D) side A is more turgid than side B
