(B) $I$. Beryllium oxide $(BeO)$ is amphoteric in nature, reacting with both acids and bases. This is a correct statement.$II$. Beryllium does not react directly with hydrogen to form $BeH_2$. This is an incorrect statement.$III$. $BeH_2$ is prepared by the reaction of $BeCl_2$ with $LiAlH_4$: $2BeCl_2 + LiAlH_4 \rightarrow 2BeH_2 + LiCl + AlCl_3$. This is a correct statement.$IV$. Beryllium sulphate $(BeSO_4)$ is highly soluble in water due to the high hydration enthalpy of the small $Be^{2+}$ ion. It is not the least soluble. This is an incorrect statement.Therefore, statements $I$ and $III$ are correct.
