Which one is not correct mathematical equation for Dalton's Law of partial pressure ? Here `` p= `` total pressure of gaseous mixture

(A) `` p _{i}=\chi_{i} p _{i}^{0} `` , where `` \chi_{i}= `` mole fraction of `` i^{\text {th }} `` gas in gaseous mixture `` p_{i}^{0}= `` pressure of `` i^{\text {th }} `` gas in pure state
(B) `` p = p _{1}+ p _{2}+ p _{3} ``
(C) `` p = n _{1} \frac{ RT }{ V }+ n _{2} \frac{ RT }{ V }+ n _{3} \frac{ RT }{ V } ``
(D) `` p _{i}=\chi_{i} p `` , where `` p _{j}= `` partial pressure of `` i^{\text {th }} `` gas `` \chi_{i}= `` mole fraction of `` i^{\text {th }} `` gas in gaseous mixture
