Solution

The correct option is B Weight fraction of solute
Temperature will affect the volume of solution.
Hence, the expression for concentration that contain volume will change with temperature. Hence weight fraction of solute changes.
i.e. , Molarity gets effected with the change in temperature because the number of moles per unit volume changes by the change in temperature.
