Match List I with List II.
List I With Ore       List II Composition
(A) Siderite             (I) FeCO$$_3$$
(B) Malachite         (II) CuCO$$_3$$ · Cu(OH)$$_2$$
(C) Sphalerite         (III) ZnS
(D) Calamine          (IV) ZnCO$$_3$$
Choose the correct answer from the options given below:

We need to match each ore with its correct composition.

Recall the compositions of each ore. Siderite is an iron ore with the formula FeCO₃, which corresponds to (I). Malachite is a copper ore with the formula CuCO₃·Cu(OH)₂ (basic copper carbonate), matching (II). Sphalerite, also called zinc blende, is a zinc ore with the formula ZnS and corresponds to (III). Calamine is a zinc ore with the formula ZnCO₃, matching (IV).

Therefore, the matching is A-I, B-II, C-III, D-IV. The answer is Option A: A-I, B-II, C-III, D-IV.
