Given reaction,
\[
\begin{array}{l}
2 \mathrm{~K}_{4}\left[\mathrm{Fe}(\mathrm{CN})_{6}\right](a q)+\mathrm{H}_{2} \mathrm{O}_{2}(a q) \rightarrow \\
2 \mathrm{~K}_{3}\left[\mathrm{Fe}(\mathrm{CN})_{6}\right](a q)+2 \mathrm{KOH}(a q) \\
\end{array}
\]
The above given reaction is oxidation reaction due to
(a) removal of a hydrogen from \( \mathrm{H}_{2} \mathrm{O}_{2} \)
(b) addition of electropositive potassium to \( \mathrm{H}_{2} \mathrm{O}_{2} \)
(c) removal of electropositive element potassium from potassium ferrocyanide \( \left(\mathrm{K}_{4}\left[\mathrm{Fe}(\mathrm{CN})_{6}\right]\right) \)
(d) All of the above are the correct reasons.
