Best answer
Right choice is (b) False

Best explanation: Investment casting is a very expensive process for producing castings because of larger manual labour involved in the preparation of the pattern and the mould. And this process is also limited by the size and mass of the casting. The maximum limit on the mass of casting may be of the order of 5 kg.
