Question

Match LIST I with LIST II
LIST I (Metal)
(A) Manganese
(B) Zinc
(C) Aluminium
(D) Lithium
LIST II (Ore)
(I) Sinsilfuoride (typo)
(II) Gibbsite
(III) Lepidolite
(IV) Psilomelane

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

Hint:

Focus on the definite pairs first when matching: - Aluminium \(\rightarrow\) Bauxite/Gibbsite - Lithium \(\rightarrow\) Lepidolite/Spodumene - Manganese \(\rightarrow\) Psilomelane/Pyrolusite - Iron \(\rightarrow\) Hematite/Magnetite

Answer 1

The Correct Option is C

Step 1: Analyze Aluminium (C)
The primary ore of aluminium is bauxite, which is a rock composed mainly of aluminium hydroxide minerals, the most common of which is Gibbsite. Thus, C matches with (II).

Step 2: Analyze Lithium (D)
Lithium is commercially extracted from several minerals, including spodumene and Lepidolite, which is a lithium-bearing mica. Thus, D matches with (III).

Step 3: Analyze Manganese (A)
Major ores of manganese include pyrolusite and Psilomelane. Thus, A matches with (IV).

Step 4: Analyze Zinc (B)
The main ore of zinc is sphalerite (zinc sulfide). "Sinsilfuoride" (I) is not a recognized mineral and is likely a typo. By elimination based on the other correct matches, B is paired with I. Conclusion: The matching is A-IV, C-II, D-III. Option (C) contains this pattern (A-IV, B-I, C-II, D-III).
