Best answer
Correct answer is (a) Glass-fiber reinforced

The best explanation: When fibers are used as a dispersed phase for the reinforcement of matrices, the resultant composites are known as glass-fiber reinforced. Glass-fiber reinforced composites should have low density, high impact resistance, high tensile strength and excellent chemical and corrosion resistance.
