The advantage(s) of using $${O}_{2}$$ rather than air in the steel industry is (are): $$(I)$$ There is a faster conversion, so a given plant can produce more in day $$(II)$$ Larger quantities can be handled $$(III)$$ It gives a pure product, and the surface is free from nitrides.

A$$I$$ only
B$$II$$ and $$III$$ only
C$$II$$ only
Correct Answer
