Solution
The correct option is A Carbon
A reducing environment (often provided by carbon monoxide in an air-starved furnace) pulls the final oxygen atoms from the raw metal. Lead is usually smelted in a blast furnace, using the lead sinter produced in the sintering process and coke to provide the heat source.
Hence as stated above coke(Carbon) is added in blast furnace to reduce lead. So,option A is correct answer.
