Solution
The correct option is B bitumen
Bitumen is an oil-based substance. It is a semi-solid hydrocarbon product produced by removing the lighter fractions (such as liquid petroleum gas, petrol, and diesel) from heavy crude oil during the refining process.
As such, it is correctly known as refined bitumen. It is used as a road paving material. The vast majority of refined bitumen is used in construction: primarily as a constituent of products used in paving and roofing applications. According to the requirements of the end-use bitumen is produced to specification.
