b) There cannot be water inside only because it would mean starch and albumin diffused out and they cannot pass through the bag

c) This is correct. The bag isn't permeable to albumin so it stays inside

d) Albumin cannot be outside the bag because the bag isn't permeable to albumin. The albumin stays inside

e) Starch cannot be outside the bag because the bag isn't permeable to starch. The starch stays inside
