What condition causes the undesirable production of carbon monoxide (CO) during a fire?

Answer

An insufficient oxygen supply, leading to incomplete combustion.

When the oxygen supply is insufficient, the reaction becomes incomplete, resulting in less efficient energy release and the production of byproducts like carbon monoxide and smoke.
