Answer:
b water will move out of the bag and it will shrink
Explanation:
Water moves from a high concentration to a low concentration across a semi-permeable membrane. The concentration of water inside the bag in 90% (because it is 10% sugar). The concentration of water outside the bag is 30%, (because it is 70% sugar).
Therefore, the concentration of water is higher inside the bag than outside. Water will move out of the bag, causing it to shrivel up.
