Principles Related to Practical Chemistry: JEE Main 2025 Chemistry question

Given below are two statements: Statement I: In the oxalic acid vs $\mathrm{KMnO_4}$ (in the presence of dil $\mathrm{H_2SO_4}$) titration the solution needs to be heated initially to 60°C, but no heating is required in Ferrous ammonium sulphate (FAS) vs $\mathrm{KMnO_4}$ titration (in the presence of dil $\mathrm{H_2SO_4}$) Statement II: In oxalic acid vs $\mathrm{KMnO_4}$ titration, the initial formation of $\mathrm{MnSO_4}$ takes place at high temperature, which then acts as catalyst for further reaction. In the case of FAS vs $\mathrm{KMnO_4}$, heating oxidizes $\mathrm{Fe^{2+}}$ into $\mathrm{Fe^{3+}}$ 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
