Vedclass · Answer

(C) Elements in group $III$ (or group $13$) typically exhibit a valency of $3$ due to their valence shell configuration of $ns^2 np^1$.When these elements react with oxygen,they form oxides with the general formula $R_2O_3$,where $R$ is in the $+3$ oxidation state.For example,Aluminum $(Al)$ belongs to group $III$ and forms Aluminum oxide $(Al_2O_3)$.Therefore,the correct statement is that it forms $R_2O_3$.
