Question

Match the mineral groups with examples:

List I	List II
A. Oxide --- IV. Quartz B. Silicate --- II. Feldspar C. Carbonate --- I. Siderite D. Sulphide --- III. Galena	IV. Quartz II. Feldspar I. Siderite III. Galena

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

Hint:

Key examples: Siderite (FeCO$_3$) = carbonate; Galena (PbS) = sulphide; Feldspar = silicate; Quartz = oxide/silicate as given.

Answer 1

The Correct Option is C

Step 1: Concept
Mineral classification by chemical composition.

Step 2: Meaning
Minerals are classified into oxides, silicates, carbonates, sulphides, etc. based on their anion/structural unit.

Step 3: Analysis
Note: The question maps Oxide to Quartz (IV) --- while Quartz (SiO$_2$) is technically a silicate/oxide, it is paired as given. Following the question's given pairings: Oxide (A): Quartz (SiO$_2$) --- IV.
Silicate (B): Feldspar (KAlSi$_3$O$_8$) --- II.
Carbonate (C): Siderite (FeCO$_3$) --- I.
Sulphide (D): Galena (PbS) --- III.

Step 4: Conclusion
Following the question's mapping: A-IV, B-II, C-I, D-III. Final Answer: (C)
