Based on the given diagram, which of the following statements regarding the homogenous solutions of two volatile liquids are correct?
(1) Plots \( A D \) and \( B C \) show that Raoult's law is obeyed for the solution in which \( B \) is a solvent and \( A \) is the solute and as well as for that in which \( A \) is solvent and \( B \) is solute.
(2) Plot \( C D \) shows that Dalton's law of partial pressures is obeyed by the binary solution of components \( A \) and \( B \).
(3) \( E F+E G=E H \); and \( A C \) and \( B D \) correspond to the vapour pressures of the pure solvents \( A \) and \( B \) respectively.
(a) Only 1
(b) 2 and 3
(c) 1 and 3
