A dilute ferrous sulphate solution was gradually added to the beakercontaining acidified permanganate solution. The light purple colour of the solutionfades and finally disappears. Which of the following is the correct explanation for theobservation?(a) KMnO 4 is an oxidizing agent, it oxidizes FeSO 4(b) FeSO 4 acts as an oxidizing agent and oxidizes KMnO 4(c) The colour disappears due to dilution, no reaction is involved(d) KMnO 4 is an unstable compound and decomposes in the presence of FeSO 4 to acolourless compound
