Flower cell is hypertonic to fresh water, this means that the amount of solute in the solution outside the flower cell is higher than the solute content inside the flower cell.
While when a flower cell is hypotonic, it means that the amount of solute in the solution outside the flower cell is lower than the solute content inside the flower cell.
This is the reason why a flower plant placed in vase of water stood and become erect, while the same flower placed in a salt solution wilted.
Hence, option A is correct
