Statement `KMnO_(4)` acts as oxidant as well as self indicator in its titration with Ferrous ammonium sulphate solution in acidic medium.  Explanation `KMnO_(4)` reduces itself to `Mn^(2+)` ions and oxidises `Fe^(2+)` to `Fe^(3+)` as well as after redox reaction is complete, the `KMnO_(4)` at the equivalence point imparts pink colour.
