What action should you take when parking and leaving your car?

Answer: B — Engage the steering lock

Engaging the steering lock is an important action when parking and leaving your car. This mechanism helps prevent theft by making it more difficult for someone to steer the vehicle if they attempt to take it without your permission. By locking the steering wheel in place, you add an extra layer of security that deters potential car thieves. While turning off the engine and using your alarm system are also good practices, they do not provide the same physical barrier against unauthorized movement of the vehicle that the steering lock does. Leaving the doors unlocked would negate your efforts to secure the car, making it more vulnerable to theft. Therefore, engaging the steering lock is a crucial step in ensuring your vehicle remains secure while it is parked.
