Best answer
Right choice is (d) Fine tooling

Easy explanation: Fine tooling involves removing projections till a fairly smooth surface is obtained. In pitch faced dressing, the edges are levelled and the flaws on the face of the stone is allowed to remain. In furrowed finish, a fixed margin is sunk on all sides with a central portion projecting. In the combed finish, a comb with steel teeth is rubbed on the surface.
