Which of the following is the expression of Raoult’s law? (`p^(o)` = vapour pressure of pure solvent, `p^(s)` = vapour pressure of the solution)

A

`(p^(o) - p^(s))/(p^(o)) = (n)/(n+N)`

B

`(p^(s) - p^(o))/(p^(o)) = (N)/(N+n)`

C

`(p^(o) - p^(s))/(p^(o)) = (N)/(N-n)`

D

`(p^(s) - p^(o))/(p^(s)) = (N-n)/(N)`
