Four freshly cut potato cylinders were left in different salt solutions for one hour and then fixed to cork blocks with pins. Two of the blocks are shown. Which solution would make the potato cylinder the most flaccid?
- A$0.1\ \text{mol dm}^{-3}$ salt solution
- B$0.3\ \text{mol dm}^{-3}$ salt solution
- C$0.7\ \text{mol dm}^{-3}$ salt solution
- D$1.0\ \text{mol dm}^{-3}$ salt solution
