Explain why can alkali and alkaline earth metals not be obtained by chemical reduction methods?

Options

1. ABecause alkali and alkaline earth metals are highly reactive and readily react with reducing agents.
2. BBecause alkali and alkaline earth metals have low ionization energies, making them difficult to reduce chemica
3. CBecause alkali and alkaline earth metals have high ionization energies, making them difficult to reduce chemic
4. DBecause alkali and alkaline earth metals have high melting points, making them difficult to reduce chemically.
