1.	Element of group 14. (a) exhibit oxidation state of +4 only (a) exhibitoxidationstate of +4 only , (b) exhibitoxidationstate of +2 and +4 (c ) form M^(2-) and M^(4+) ion , (d) form M^(2+) and M^(4+) ions.
Answer» Solution :DUE toinertpaireffect, elementof group 14exhibit oxidationstates of `+2` and `+4`. Thus option (B) ISCORRECT.
