Match List - I with List - II.

List-I (Metal)	List-II (Ores)
(a) Aluminium	(i) Siderite
(b) Iron	(ii) Calamine
(c) Copper	(iii) Kaolinite
(d) Zinc	(iv) Malachite

Choose the correct answer from the options given below:

We need to match each metal with its correct ore.

Aluminium is found in Kaolinite, which is a clay mineral with the formula $$Al_2Si_2O_5(OH)_4$$. So (a) matches with (iii).

Iron is found in Siderite, which has the formula $$FeCO_3$$. So (b) matches with (i).

Copper is found in Malachite, which has the formula $$Cu_2(OH)_2CO_3$$ (basic copper carbonate). So (c) matches with (iv).

Zinc is found in Calamine, which is $$ZnCO_3$$ (zinc carbonate). So (d) matches with (ii).

Therefore, the correct matching is: (a)-(iii), (b)-(i), (c)-(iv), (d)-(ii).

The correct answer is Option (4).
