A student dissolved 5 g of sugar in 100 mL of distilled water in beaker A. He dissolved 100 g of sugar in 100 mL of distilled water in beaker B. Then he dropped a few raisins of equal weight in each beaker. After two hours he found the raisins in A swollen and those in B shrunken. The inference drawn is that:

A

sugar concentration of raisins is lower than that of solution A and higher than that of solution B.

B

sugar concentration of raisins is higher than that of solution A and lower than that of solution B.

C

in B the cell membrane of raisins was damaged resulting in bleaching

D

in A the permeability of water of the cell membrane of raisins was enhanced
