A) C
B) Al
C) Electrolytic reduction
D) Cu
Correct Answer: A
Solution :
[a] C Direct reduction of iron ores, i.e. hematite, magnetite etc. Which might have escaped reduction around 823K, gets completely reduced to iron by carbon above 1123K. \[F{{e}_{2}}{{O}_{3}}(s)+3l\,(s)\,\xrightarrow{>1123\,K}\text{ }2Fe\,(s/l)+3CO\,(g)\]
