$P_A$ and $P_B$ are the vapour pressure of pure liquid components, A and B, respectively of an ideal binary solution. If $X_A$ represents the mole fraction of component A, the total pressure of the solution will be:

Question

( A ) $P_B+X_A(P_B-P_A)$
( B ) $P_B+X_A(P_A-P_B)$
( C ) $P_A+X_A(P_B-P_A)$
( D ) $P_A+X_A(P_A-P_B)$
