Correct answer: B. Stop where safe and investigate the cause.
If a driver notices steam rising from the engine compartment of their vehicle, they should stop where safe and only investigate the cause once it has cooled down. Do not remove a radiator or header tank cap when the engine is hot. Steam rising from the engine is an indication that the engine is overheating and it should not continue to be driven. Refer to the vehicle handbook for further information and guidance or seek advice from a competent person.
