(i) II > I

${\text{CH}}_{\text{3}}-\stackrel{\oplus }{\text{CH}}-\text{O}-{\text{CH}}_{\text{3}}\leftrightarrow {\text{CH}}_{\text{3}}-\text{CH}=\stackrel{\oplus }{\text{O}}-{\text{CH}}_{\text{3}}$

After resonance octet will complete in that compound

(ii) I > II

$\mathrm{I}\to \mathrm{\alpha }\mathrm{H}=5$

$\mathrm{I}\mathrm{I}\to \mathrm{\alpha }\mathrm{H}=2$

I is more the stability of the compound

(iii) II > I

II is more stable due to resonance

(iv) II > I

Due to octet complete after resonance in the compound.
