Both Statement $I$ and Statement $II$ are correct.

Vedclass · Answer

(C) Statement $I$ is correct: Lithium $(Li)$ and Magnesium $(Mg)$ have high charge density and small ionic sizes,which prevents the formation of larger superoxide ions. They typically form normal oxides ($Li_2O$ and $MgO$).
Statement $II$ is correct: The ionic radius of $Li^{+}$ is $76 \ pm$ $(0.76 \ \mathring{A})$ and the ionic radius of $Mg^{2+}$ is $72 \ pm$ $(0.72 \ \mathring{A})$. Since $76 \ pm$  >  $72 \ pm$,the ionic radius of $Li^{+}$ is indeed larger than that of $Mg^{2+}$.
Therefore,both statements are correct.
