Which of the following describes the function of air bags?

Answer: B — To provide cushioning during a crash

Airbags are a crucial safety feature in vehicles designed primarily to provide cushioning during a crash. They deploy rapidly in the event of a collision, acting as an additional protective barrier between the occupants and hard surfaces within the vehicle, such as the steering wheel, dashboard, and windows. The deployment of airbags helps to reduce the risk of injury by absorbing some of the force of impact, thereby minimizing the potential for severe trauma to the head, neck, and chest. While the other options mention important vehicle functions, they do not relate to the intended purpose of airbags. For instance, inflating tires and maintaining tire pressure are related to tire management and vehicle performance, while preventing passengers from sliding is more closely associated with seat belts and other restraint systems. Therefore, the option that highlights the cushioning aspect of airbags accurately reflects their primary function in enhancing passenger safety during accidents.
