Oxalic acid on reacting with acidified

\mathrm{KMn}{\mathrm{O}_4}

is oxidised to :

View answer and explanation

Correct option: C

\mathrm{C}{\mathrm{O}_2}\,and\,{\mathrm{H}_2}\mathrm{O}

Option C (

\mathrm{C}{\mathrm{O}_2}\,and\,{\mathrm{H}_2}\mathrm{O}

) is correct because oxalic acid is oxidized to carbon dioxide and water by acidified potassium permanganate.
