Solution

The correct options are
B Carbon monoxide
C Carbon dioxide
When coal is burnt in a closed room, the supply of oxygen is limited causing incomplete combustion. This leads to the formation of carbon monoxide $(C O)$ gas.

Apart from this, a small amount of carbon dioxide $(C O_{2})$ is also produced as some carbon atoms undergo complete combustion as well.
