Solution
The correct options are
B Iron
D Lead
Calcium and magnesium are more reactive than carbon. So, they cannot be extracted by reducing their metal oxides using carbon. Rather they are extracted by electrolytic reduction process.
Iron and lead are less reactive than carbon. So, they can be extracted by reducing their metal oxides using carbon.
