Solution

The correct option is C CO
Coke is used as a fuel and as reducing agent in smelting iron ore in a blast furnace. The CO produced by its combustion reduces iron oxide (hematite) in the production of iron product. Coke can be combusted producing little or no smoke while bituminous coal will produce much more smoke.
