Best answer
Right option is (b) False

The explanation: Injection moulding is very advantageous when it needs to manufacture intricate parts in abundant quantity. In injection moulding machine, components are often moulded directly in the machine with surface finish and other features like color thereby excluding the secondary finish, which also excludes the cost of further machining.
