Major ore of lead is:
Correct answer: B. Galena
- A. Anglesite
- B. Galena
- C. Cerussite
- D. Azurite
Explanation
Option B is correct. Galena is the major ore of lead. It is a lead sulfide mineral with the chemical formula PbS. Galena is commonly found in hydrothermal veins, sedimentary rocks, and some types of metamorphic rocks. The other options, such as Anglesite, Cerussite, and Azurite, are not the major ores of lead and are different mineral compounds.
