Question:

Match List I with List II

List I List II
 A. Calamine I. \(CuFeS_2\)
B. Siderite II. \(ZnCO_3\)
C. Sphalerite III. \(ZnS\)
D. Copper pyrite IV. \(FeCO_3\)

Choose the correct answer from the options given below:

Options:

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

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

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

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

Correct Answer:

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

Explanation:

The correct answer is option 3. A-II, B-IV, C-III, D-I.

List I List II
 A. Calamine II. \(ZnCO_3\)
B. Siderite IV. \(FeCO_3\)
C. Sphalerite III. \(ZnS\)
D. Copper pyrite I. \(CuFeS_2\)


A. Calamine - This mineral is zinc carbonate (\(ZnCO_3\)). Calamine is a mineral composed of zinc carbonate, which often occurs in massive or granular form. It is an important ore of zinc.

B. Siderite - This mineral is iron carbonate (\(FeCO_3\)). Siderite is a mineral composed of iron carbonate. It typically forms brownish to tan rhombohedral crystals but can also occur in massive or granular forms. Siderite is an important ore of iron.

C. Sphalerite - This mineral is zinc sulfide (\(ZnS\)). Sphalerite is a mineral composed of zinc sulfide. It is the primary ore of zinc and is often found associated with galena, another important ore mineral.

D. Copper pyrite - This mineral is copper iron sulfide (\(CuFeS_2\)), also known as chalcopyrite. Chalcopyrite is the most important ore of copper. It typically has a brassy yellow color and often forms crystals with a tetragonal or pseudocubic habit.

So, the correct match is: A-II, B-IV, C-III, D-I
