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)
