C		III	Elastomers
D		IV	Thermoplastic polymer

Choose the correct answer from the options given below

Type of polymers on the basis of molecular forces operating between different polymer chains, the polymers are of the following types: Elastomers: (Example: vulcanized rubber, natural rubber, etc) Fibers: (Example: nylon, Orlon, polyesters) Thermoplastics Polymers: (Example: polypropylene, polythene, etc)
