Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding tungsten minerals.
Tungsten occurs mainly in the minerals scheelite (CaWO\textsubscript{4}) and wolframite ((Fe,Mn)WO\textsubscript{4}). These are the principal ores of tungsten.
Step 2: Comparing the options.
(A) Bornite: A copper-iron sulfide mineral (Cu\textsubscript{5}FeS\textsubscript{4}).
(B) Cassiterite: Tin oxide (SnO\textsubscript{2}), main ore of tin.
(C) Scheelite: Calcium tungstate (CaWO\textsubscript{4}), an important tungsten ore.
(D) Greenockite: Cadmium sulfide (CdS), ore of cadmium.
Step 3: Conclusion.
The correct answer is (C) Scheelite, as it contains tungsten.
