Options:(select one or more)
Answer:
B, C
Solution:
CO can reduce oxides of metals that are below it in reactivity series and are moderately stable.
PbO and FeO are reduced by CO to Pb and Fe respectively.
CaO and MgO are very stable oxides (alkaline earth metals), so CO cannot reduce them.
Hence correct answer is (B) PbO and (C) FeO.
