B. exhibit oxidation state of + 2 and + 4

C. form M2– and M4+ ions

D. form M2+ and M4+ ions

Answer :

The elements of group 14 have 4 valence electrons. Therefore, the oxidation state of the group is + 4. However, as a result of inert pair effect, the lower oxidation state becomes more and more stable and the higher oxidation state becomes less stable.
