Match Column $(A)$ with the appropriate options in Column $(B)$.

Column $(A)$	Column $(B)$
$(a)$ $BeO$	$(p)$ Amphoteric
$(b)$ $MgCO_3 \cdot CaCO_3$	$(q)$ Dolomite
$(c)$ $BeCl_2$	$(r)$ Covalent
$(d)$ $Al(OH)_3$	$(s)$ Basic

(A) $(a)-(p, s), (b)-(q), (c)-(r), (d)-(p)$
$1$. $BeO$ is amphoteric and basic in nature.
$2$. $MgCO_3 \cdot CaCO_3$ is known as Dolomite.
$3$. $BeCl_2$ is a covalent compound due to the small size and high polarizing power of $Be^{2+}$ ion.
$4$. $Al(OH)_3$ is amphoteric in nature.
