The correct option is
B (I) Mass by mass percentage, (II) Mass by volume percentage
There are various ways of expressing the concentration of a solution.
(I) Concentration in terms of mass by mass percentage =Mass of soluteMass of solution×100
II) Concentration in terms of mass by volume percentage =Mass of soluteVolume of solution×100
III) Concentration in terms of volume by volume percentage =Volume of soluteVolume of solution×100
