Acetone and carbon disulphide form binary liquid solution showing positive deviation from Raoult's law. The normal boiling point `(T_(b))` of pure acetone is less than that of pure `CS_(2)`. Pick out the incorrect statement among the following :

Options

A. Boling temperature of mixture is always less than boiling temperature of acetone
B. Boiling temperature of mixture is always less than boiling temperature of acetone.
C. When a small amount of `CS_(2)` (less volatile component) is added to excess of acetone boling point of resulting mixture increases.
D. A mixture of `CS_(2)` and `CH_(3)COCH_(3)` can be completely separated by simple fractional distillation.
