Right choice is (b) False

The explanation: Not only sand moulds, the metallic moulds can also be used in the centrifugal casting process for large scale production. As inducing of high temperature of metallic mould can be avoided by water circulation through it and sticking problem can also be solved by casting of non-sticking materials.
