(B) $1$. Calamine is $ZnCO_3$ and siderite is $FeCO_3$. Both are carbonate ores. (Correct)$2$. Argentite is $Ag_2S$ (sulphide) and cuprite is $Cu_2O$ (oxide).

Malachite is $Cu(OH)_2 \cdot CuCO_3$ and azurite is $Cu(OH)_2 \cdot 2CuCO_3$. Both are copper ores. (Correct)Therefore,the incorrect statement is $B$.
