Best answer
Right choice is (c) Buffing

For explanation I would say: Some of the basic forming and fabrication techniques for rubber include compression molding, calendering, injection and transfer molding, and extrusion among others. Tumbling, trimming, and buffing are techniques of finishing this fabricated rubber.
