B Chalcopyrites ii $Z n C O_{3}$

C Bauxite iii $F e_{2} O_{3}$

D Haematite iv $A l_{2} O_{3} 2 H_{2} O$

Tlie correct match is

A - (II) ,B - (I) , C - (IV) , D -(III)

A - (I) ,B - (III) , C - (IV) , D -(II)

A - (III) ,B - (I) , C - (II) , D -(IV)

A - (I) ,B - (III) , C - (II) , D -(IV)

$∵$ Formula of given ores are as follows :
(A) Calamine $= Z n C O_{3}$
(B) Chalcopyrite $= C u F e S_{2}$
(C) Bauxite $= A l_{2} O_{3} \cdot 2 H_{2} O$
(D) Haematite $= F e_{2} O_{3}$
