Best answer
The correct option is (d) Cement

The explanation: Ash is widely used in the production of cement. Fly ash is pozzolanic and develops self hardening characteristics. Concrete made of ash can yield improved workability and strength greater than all cement based concrete. The pozzolanic quality of ash lime mixture creates a healing of cracks in the pavement themselves.
