Redox Reactions

Given below are two statements :

Statement I: In the oxalic acid vs KMnO4 (in the presence of dil H2SO4 ) titration the solution needs to be heated initially to 60∘C, but no heating is required in Ferrous ammonium sulphate (FAS) vs KMnO4 titration (in the presence of dill H2SO4 )
Statement II : In oxalic acid vs KMnO4 titration, the initial formation of MnSO4 takes place at high
temperature, which then acts as catalyst for further reaction. In the case of FAS vs KMnO4, heating oxidizes Fe2+ into Fe3+ by oxygen of air and error may be introduced in the experiment.

In the light of the above statements, choose the correct answer from the options given below
