Answer 2

The correct answer is option (4) M+S.

Explanation:

• A metal {(M) = (Noble gas configuration) (n-1)d'ºns?np*} shows only two oxidation number M. and M".
• If polarizing power of Mat is M+S.
• If we take 2e-s from each of the above configurations, we notice that only (Z=25) leads to the formation of M2+ with 5 unpaired electrons.
• Hence, the correct answer is option (4) M+S.
