The correct answer is B. Calamine.
Calamine is a zinc carbonate mineral with the chemical formula ZnCO3. It is a white, earthy mineral that is often found in association with other zinc minerals, such as sphalerite and zincite. Calamine is an important ore of zinc and is used in the production of zinc metal, zinc oxide, and zinc salts.
Zinc blende, sphalerite, and zincite are all zinc sulfide minerals. Zinc blende is the most common zinc ore and is the principal source of zinc metal. Sphalerite is a black or brown mineral that is often found in association with galena, a lead sulfide mineral. Zincite is a red or brown mineral that is often found in association with sphalerite.
Zinc blende, sphalerite, and zincite are all important ores of zinc, but calamine is the only carbonate ore of zinc.
