Best answer
The correct choice is (a) True

The explanation is: Epoxies can be used in various ways. In adding with glass fibers, it is capable of making composites that are of high strength and heat resistant. These composites are basically used for making motor casings in missiles, aircraft parts, fixtures etc. Epoxies are also found in industrial equipment and in protective coatings of appliances.
