Universal gas constant is

Different curves in the figure show the behaviour of gases

(i) Curve I represent ideal gas behaviour
(ii) Curves II, III and IV also represents ideal gas behaviour at different temperatures $T_2,T_3$ and $T_4$
(iii) Curves II, III and IV represents behaviour of a real gas at different temperatures $T_2,T_3$ and $T_4$
(iv) $T_2>T_3>T_4$
(v) $T_2<T_3<T_4$
The correct statements are

Two non-reactive monatomic ideal gases have their atomic masses in the ratio $2:3$. The ratio of their partial pressures, when enclosed in a vessel kept at a constant temperature is $4:3$. The ratio of their densities is
