The Correct Option is A

Solution and Explanation

Basalt, laterite and granite are natural stones that can be cut or quarried into blocks and used directly in walls.
Fly ash is a fine powder, a by-product of coal-fired power plants, and it cannot form a wall in its original form; it must be processed (for example into fly ash bricks or blocks or mixed with cement).
Answer: (1) Fly ash
