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

where pi = partial pressure of ith gas

$${\chi _i}$$ = mole fraction of ith gas in gaseous mixture where $${\chi _i}$$ = mole fraction of ith gas in gaseous mixture

$$p_i^o$$ = pressure of ith gas in pure state

A
$$p = {p_1} + {p_2} + {p_3}$$
B
$$p = {n_1}{{RT} \over V} + {n_2}{{RT} \over V} + {n_3}{{RT} \over V}$$
C
$${p_i} = {\chi _i}p$$
D
$${p_i} = {\chi _i}p_i^o$$
