If `P^(@)` and `P_(5)` are the vapour pressure of the solvent and its solution respectively and `x_(1)` and `x_(2)` are the mole fraction of the solvent and solute respectively, then
A. `P_(s) = P^(@) 2x_(2)`
B. `P^(@) - P_(s) = P^(@)x_(2)`
C. `P_(s) = P^(@)x_(1)`
D. `(P^(@)-P_(s))//P_(s)=x_(1)//(x_(1)+x_(2))`

Correct Answer - B::C
`P_(s)=P^(@)x_(1)`
`P_(s)=P^(@)(1-x_(2))`
`P_(s)=P^(@)-P^(@)x_(2)`
`P^(@)-P_(s)=P^(@)x_(2)`
