We can understand from the above discussion that iron oxide is reduced by carbon monoxide. So, the correct answer is "Option B". Note: > A blast furnace is generally used during the extraction of pig iron from ores but it is also used for extraction of copper and lead.

It's unusual and inefficient to ingest elemental iron (Fe 0) as ones source of dietary iron.Usually it would be in it's oxidized Fe 3+ or partially reduced Fe 2+ forms in various organic complexes which your body would break down and use for its own purposes. In hemoglobin Fe 2+ is temporarily oxidized by O*2* to Fe 3+.. Rust is indeed an iron oxide (usualy Fe*2O3* with oxidized Fe 3+).

We report here that iron oxide can be reduced completely to elemental iron, through a carbon-free and low-temperature reaction. Nanoparticles of Fe 2 O 3 are completely reduced, resulting in the formation of nanoparticles of Fe, on the surfaces of Si or Ge, at ∼740 and ∼440 °C respectively. We show that this phenomenon is due to the oxygen atoms changing the bonding partner from Fe to Si ...
