Solution

The correct option is C Both (a) and (b)
$R u \to [K r] 4 d^{7} 5 s^{1}$
Oxidation number in combined state = +8
Example: $R u O_{4} \to x + 4 \times (- 2) = 0 \Rightarrow x = + 8$

$O s \to [X e] 4 f^{14} 5 d^{6} 6 s^{2}$
Oxidation number is combined state = +8
Example ; $O s O_{4} \to x + 4 \times (- 2) = 0 \Rightarrow x = + 8$

Note: Both $R u$ and $O s$ show +8 oxidation state but Ru will be less stable in this oxidation state.
