(B) The reaction between beryllium chloride $(BeCl_2)$ and lithium aluminium hydride $(LiAlH_4)$ is a standard method for the preparation of beryllium hydride $(BeH_2)$.The balanced chemical equation is:$2BeCl_2 + LiAlH_4 \rightarrow 2BeH_2 + LiCl + AlCl_3$Comparing this with the given equation,$X$ corresponds to $BeH_2$.

$2BeCl_2 + LiAlH_4 \rightarrow X + LiCl + AlCl_3$
