Answer»

Correct ANSWER is (a) Concrete

Explanation: Concrete is a composite MATERIAL composed of coarse aggregate BONDED together with a FLUID cement that hardens over time. Most concretes used are lime-based concretes such as Portland cement concrete or concretes made with other hydraulic cements, such as ciment fondu. However, asphalt concrete, which is frequently used for road surfaces, is ALSO a type of concrete, where the cement material is bitumen, and polymer concretes are sometimes used where the cementing material is a polymer.
