MCQ
The highest oxidation state shown by transition elements is
  • A
    $+ 7$ by $Mn$
  • B
    $+ 8$ by $Os$
  • C
    $+ 8$ by $Ru$
  • Both $(b)$ and $(c)$

Answer

Correct option: D.
Both $(b)$ and $(c)$
d
The highest oxidation state shown by any transition metal is eight which is shown by Ru and Os.

Hence Options $\mathrm{B} \& \mathrm{C}$ are correct.
