The correct answer is:
C

: Blast furnace is frequently used for the extraction of iron and copper from their ores. Carbon and carbon monoxide reduce the metallic oxides to the free metals. Slag formation plays an important role in blast furnace as it covers the melted metal and thus protects the metal from being reoxidized.
