Best answer
Correct option is (b) False

The best explanation: After baking of cores in dielectric core bakers, finishing operation is a must before they set in the moulding box. Finishing is the last process which completes the formation of a core. This is a process in which bumps or other sand projections are removed from the surfaces of cores by filing them in a fixture.
