Right option is (c) Fly ash

Best explanation: Fly ash is sold in the market, which is used in concrete bricks, cement clinkers, road subbase and as mineral filler in asphaltic concrete. Fly ash is very fine in its structure, composed mostly of silica made from burning of coal in the furnace or boiler. And ‘Bed ash’ refers to the ash that’s struck on the walls of boiler which is very coarse in nature.
