Solution

The correct option is A
Pressure composition phase diagram is the superimpose plot of $P_{T}$ vs $Y_{A}$ (curve) and $P_{T}$ vs $X_{A}$ (straight line).

The plot of $P_{T}$ vs $X_{A}$ give a straight line and it represented by the equation,
$P_{T} = (P_{A}^{0} - P_{B}^{0}) X_{A} + P_{B}^{0}$
Its in form of $y = m x + c$
$S l o p e = (P_{A}^{0} - P_{B}^{0})$
$y-intercept = P_{B}^{0}$
