Answer: A. It reduces the chances of passengers being ejected from the vehicle.

In a collision, locked vehicle doors help lower the risk of occupants being thrown out by increasing the duration over which momentum changes occur. This reduces the force experienced by the passengers. This concept relies on the physics principle of impulse, which is also used in the design of safety features such as airbags and crumple zones in modern vehicles. For instance, vehicle doors often feature several locking components—like latch hooks, striker plates, and deadbolts—that work together to ensure the door stays firmly shut in the event of an accident.
