Match List - I with List - II.

Choose the correct answer from the options given below :

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

The correct answer is option 2. (A)-(III), (B)-(I), (C)-(IV), (D)-(II).

Let us break down the matching of each ore with its corresponding metal:

A. Calamine: Calamine is a zinc ore. It primarily consists of zinc carbonate \((ZnCO_3\) and is a significant source of zinc metal.

B. Malachite: Malachite is an ore of copper. It is a green carbonate mineral with the chemical formula \(Cu_2CO_3(OH)_2\) and is a major source of copper.

C. Siderite: Siderite is an iron ore. It is an iron carbonate mineral with the chemical formula \(FeCO_3\) and is an important source of iron.

D. Cryolite: Cryolite is an ore of aluminum. It is a mineral consisting of sodium aluminum fluoride, with the chemical formula \(Na_3AlF_6\). Cryolite was historically used as a flux in the production of aluminum.

Therefore, the correct match is:

(A) Calamine: Ore of Zinc (III)

(B) Malachite: Ore of Copper (I)

(C) Siderite: Ore of Iron (IV)

(D) Cryolite: Ore of Aluminium (II)

This arrangement aligns with the compositions and properties of each ore and the corresponding metal extracted from it.
