The vapour pressure of the solution of two liquids \[A({{p}^{o}}=80\,mm)\] and \[B({{p}^{o}}=120\,mm)\] is found to be 100 mm when \[{{x}_{A}}=0.4\]. The result shows that

A)  solution exhibits ideal behaviour

B)  solution shows positive deviations

C)  solution shows negative deviations

D)  solution will show positive deviations for lower concentration and negative deviations for higher concentrations.
