Best answer
Right option is (b) False

The best I can explain: In the extrusion process, extruder is a machine tool or device that forces ductile and soft heated solids through die openings of the desired shape to produce a continuous film, strip, or tubes of polymer materials. In this process, many kinds of polymers like thermoplastics, thermosetting, elastomers etc. are processed with the help of extruder.
