(NONE) $SiO_2$ is an acidic oxide,so it acts as an acidic flux to remove basic impurities like $FeO$ by forming slag $(FeSiO_3)$.$FeO + SiO_2 ightarrow FeSiO_3$ (slag).Option $A$ is correct.The distance between layers in graphite is $335 \ pm$ or $3.35 	imes 10^{-8} \ cm$. Option $B$ is correct.$SiO_2$ reacts with $Na_2CO_3$ as follows:$Na_2CO_3 + SiO_2 ightarrow Na_2SiO_3 + CO_2 \uparrow$.Option $C$ is correct.In graphite,each carbon atom is $sp^2$ hybridized. Option $D$ is correct.Since all given statements are correct,there is no incorrect statement among the options provided.
