• A. Bauxite
• B. Cuprite
• C. Haematite
• D. All of these

Answer 1

The correct option is D

All of these

• The mineral which contains either metal or metal compounds in enough quantity that can be extracted easily and profitability is termed as ore.
• Bauxite is an ore of Aluminum (Al) with the chemical formula ${\mathrm{Al}}_2{\mathrm{H}}_2{\mathrm{O}}_4$.
• Cuprite or Copper(I) oxide is an ore of Copper (Cu) with the chemical formula ${\mathrm{Cu}}_2\mathrm{O}$.
• Haematite or Iron (III) oxide is an ore of Iron (Fe) with the chemical formula ${\mathrm{Fe}}_2{\mathrm{O}}_3$.

Hence, option (D) is correct. Bauxite, Cuprite, and Haematite are oxide ores.
