A student dissolved 5g of sugar in 100 ml of distilled water in beaker A . She dissolved 100ml g of sugar in 100 ml of distilled water in beaker B . Then she dropped a few raisins of equal weight in each beaker . After two hours she found the raisins in A swollen and those in B shrunken. The inference drawn is tha
a) sugar concentration of raisin is lower than that of solution A and higher than that of solution B
b) sugar concentraion of raisins is higher than that of solution A and lower than that of solution B
c) in B the cell membrane of raisin was damaged resulting in leaching
d) inA the permeab;ity to water of the cell membrane of raisins was enhanced.
