Match List I with List II

Choose the correct answer from the options given below:

A-ii, B-iv, C-i, D-iii

The correct answer is option 1. A-ii, B-iv, C-i, D-iii

Let us break down the matching of metals with their respective ores:

1. Aluminium (A) - Bauxite (ii): Bauxite is the primary ore of aluminium, containing a mixture of minerals such as gibbsite \((Al(OH)_3)\), boehmite \((AlO(OH))\), and diaspore \((α-AlO(OH))\). It is the main source of aluminium metal production.

2. Iron (B) - Siderite (iv): Siderite is a mineral composed of iron carbonate \((FeCO_3)\). While it is not the primary ore of iron used for large-scale iron production, it is still an important source of iron and is occasionally mined for iron content.

3. Copper (C) - Malachite (i): Malachite is a green copper carbonate hydroxide mineral \((Cu_2CO_3(OH)_2)\) that is a secondary mineral formed in the oxidation zones of copper ore bodies. While malachite itself is not typically mined as a primary copper ore, it is an important secondary mineral associated with copper deposits.

4. Zinc (D) - Calamine (iii): Calamine is a historic name for a mineral consisting of zinc carbonate \((ZnCO_3)\), but in modern usage, it refers to a mixture of zinc silicate \((Zn_4Si_2O_7(OH)_2·H_2O)\) and zinc oxide \((ZnO)\). It is an important source of zinc metal.

In summary, each metal is matched with its corresponding ore based on the primary mineral or mineral mixture from which the metal is extracted.
