Best answer
Right choice is (b) Centrifugal force

The best I can explain: In centrifugal casting, mould is rotated rapidly about its central axis as the metal is poured into it. Because of the centrifugal force, continuous pressure is applied to the metal as it solidifies. The slag and the other inclusions being lighter gets separated from the metal and segregates toward the centre.
