Answer: (B)
Solution
Statement I is incorrect: Cast iron is obtained by remelting pig iron with scrap iron and coke, not the other way around. Pig iron is the crude product from the blast furnace.
Statement II is incorrect: Pig iron has higher carbon content (~4%) compared to cast iron (~3%). Pig iron is the first product from iron ore reduction and contains more impurities and carbon.
Therefore, both statements are incorrect.
