| Column A (Ores) | Column B (Metals) |
| (I) Siderite | [A] Zinc |
| (II) Kaolinite | [B] Copper |
| (III) Malachite | [C] Iron |
| (IV)Calamine | [D] Aluminium |
A) (I)-[B]; (II)-[C]; (III)-[D]; (IV)-[A]
B) (I)-[A]; (II)-[B]; (III)-[C]; (IV)-[D]
C) (I)-[C]; (II)-[D]; (III)-[B]; (IV)-[A]
D) (I)-[C]; (II)-[D]; (III)-[A]; (IV)-[B]
Correct Answer: C
Solution :
| Siderite | \[FeC{{O}_{3}}\] |
| Kaolinite | \[A{{l}_{2}}{{(OH)}_{4}}S{{i}_{2}}{{O}_{5}}\] |
| Malachite | \[CuC{{O}_{3}}.Cu{{(OH)}_{2}}\] |
| Calamine | \[ZnC{{O}_{3}}\] |
