Best answer
The correct option is (c) Complex shapes

To elaborate: In investment casting method, wax is used as pattern material on which slurry is coated and then wax is taken out by melting it. This process of casting is widely used for producing complex shapes of castings. It has many other advantages like good dimensional accuracy and rapid production rate of the casting components.
