The correct option is (b) False

For explanation: Polyurethane plastics come in the category of thermosetting plastics. In this type of plastics, elasticity is generally very high. Due to this property of high elasticity, it can be used in decorative and protective coatings. The high elasticity also makes these polyurethane polymers highly resistant to any chemical attack.
