Solution

The correct option is C $K M n O_{4}$

Potassium Permanganate acts like a self indicator. In acidic medium $K M n O_{4}$ gets itself converted into $M n^{2 +}$ ion which is pink in colour. So, the appearance of pale permanent pink colour will indicate the end point of the titration.So it acts as indicator and titrant.
Hence option D is correct.
