The Correct Option is D

Solution and Explanation

Step 1: Concept Lead is primarily extracted from sulphide ores found in deep mineral deposits.

Step 2: Meaning
Various minerals contain lead, including oxides and sulphates, but industrial production relies on the most abundant source.

Step 3: Analysis
Anglesite (sulphate) and Cerussite (carbonate) are secondary ores. Rutile is a titanium ore. Galena ($PbS$) is the primary and most widely distributed ore of lead.

Step 4: Conclusion
Galena is the most common and important lead ore for metallurgical extraction. Final Answer: (D)
