Points I, II and III in the following plot respectircly comespond to 

Option: 1

\mathrm{V_{m p}~ of} ~\mathrm{H}_2(300 \mathrm{k}) \mathrm{V}_{m_p} ~of ~\mathrm{N}_2(300 \mathrm{k}) \mathrm{V}_{\text {mp of }} \mathrm{O}_2(400 \mathrm{k})


Option: 2

\mathrm{ \mathrm{V}_{\text {mp }} ~of ~\mathrm{O}_2(400 \mathrm{k}) \mathrm{V}_{m p} ~of ~\mathrm{N}_2 (300k) V_{m p}~ of ~\mathrm{H}_2(300 \mathrm{k}) }


Option: 3

\mathrm{\mathrm{V}_{m p} ~of~ \mathrm{N}_2(300 \mathrm{k}) \mathrm{V}_{m p} ~of~ \mathrm{O}_2 (400k) \mathrm{V}_{m p} ~of ~\mathrm{H}_2(300 \mathrm{k}) }


Option: 4

\mathrm{V_{m p} ~of ~\mathrm{N}_2(300 \mathrm{k}) \mathrm{V}_{m p} ~of ~\mathrm{H}_2(300 \mathrm{k}) \mathrm{V}_{m p} ~of~ O_2(400k)}

\mathrm{V_{m p}=\sqrt{\frac{2 R T}{M}} i, e V_{m p} \propto \sqrt{\frac{T}{M}} }

GAS M T(k) \mathrm{\sqrt{\frac{T}{M}}}
\mathrm{H_2} 2 300 \mathrm{ \sqrt{\frac{30}{2}}=\sqrt{150} \quad \quad (III) Highest}
\mathrm{N_2} 28 300 \mathrm{ \sqrt{\frac{30}{28}}=\sqrt{10.71} \quad \quad (III) Lowest}
\mathrm{O_2} 32 400 \mathrm{ \sqrt{\frac{400}{30}}=\sqrt{12.5} \quad \quad (I)}


So, I. comes pand, to V_{\text {mp }} of \mathrm{N_2(300 \mathrm{k})}
II. corresponds to Virp of \mathrm{O_2(400 \mathrm{k})}
III. corrrespands to \mathrm{ V_{m p}} of \mathrm{ H_2(300 \mathrm{k})}
