Movement into and out of cells — practice question

The diagram shows apparatus arranged to examine the effect of placing a $10\%$ glucose solution inside a selectively permeable bag (Visking tubing) and immersing it in water. Samples of the surrounding water were tested using Benedict’s solution after $10$ minutes and again after $20$ minutes. The change in the volume of the glucose solution was recorded after $20$ minutes. Which row is correct?

  • AAfter 10 minutes: green; After 20 minutes: blue; Volume increased
  • BAfter 10 minutes: green; After 20 minutes: orange; Volume increased
  • CAfter 10 minutes: red; After 20 minutes: orange; Volume decreased
  • DAfter 10 minutes: yellow; After 20 minutes: green; Volume decreased
