Answer 2

Answer:

option (B)

Explanation:

Blast furnace: Iron ore is melted. Lime stone is fluxing material which is added. Slag is removed. Coke is burnt to heat the ore.

Pig iron: Molten materials poured into moulds called pigs

Steel making: Pig iron is further purified by melting and oxidising the impurities. Mn, Ni, Cr are added.

Shaping metal: Rolling, pressing, casting and forging
