• D. (a)-(ii) (b)-(iv) (c)-(i) (d)-(iii)

Answer 1

Answer: (B)

In the given options
The metal which reveals a maximum number of oxidation state $\to Mn$
The metal although placed in 3d block is considered not as a transition element is $\to Zn$
The metal which does not exhibit variable oxidation state is $\to SC$ (only +3)
The metal which in +1 oxidation state in aqueous solution undergoes disproportionation is $\to Cu$
