Problem
During a frontal collision, an airbag inflates in front of the driver. Why does this reduce the chance of serious injury?
(a) It locks the driver firmly in one position, preventing any forward motion.
(b) It increases the time taken to bring the driver to rest, reducing the force on the body.
(c) It removes the driver’s inertia completely by absorbing it.
(d) It pushes the driver sideways, away from the steering wheel at once.
