Best answer
Right option is (b) False

Best explanation: In the extrusion process, extruders are equipped with a screw as their main mixing part. Screw extruders are mainly of two types which are single and multiple screw extruders. In most of the cases, single screw extruders are used for the processing of polymer materials in the industries, because of its simple design, low cost and high reliability.
