Options

  1. Atin from S ⁡ n {O ⁡}_{2}
  2. Biron from {\text{Fe}}_{2} {O ⁡}_{3}
  3. Caluminium from Al2O3{\text{Al}}_{2} {O }_{3}
  4. Dmagnesium from {\text{MgCO}}_{3} · {\text{CaCO}}_{3}

Correct answer

C. aluminium from Al2O3{\text{Al}}_{2} {O }_{3}

Step-by-step solution

Smelting : The process of extracting a metal in the state of fusion is called smelting. In this process the ore is mixed with carbon, obtained after the above reactions and heated in suitable furnace.

SnO2 and Fe2O3 are reduced by C reduction method.
Al2O3 and MgCO3. CaCO3 are reduced by electrolytic reduction.
