In seat belts equipped with an emergency automatic inertia-locking retractor:
AThe retractor does not allow the belt length to be adjusted automatically, remaining always locked;
BThe pre-tensioner adjustment is manual;
CThe retractor automatically adjusts the belt length, and in case of sudden deceleration, it locks.Correct
Explanation
Seat belts equipped with an emergency automatic inertia-locking retractor allow the occupant freedom of movement under normal driving conditions, automatically adjusting the length of the strap to the body. However, in the event of sudden deceleration, emergency braking, or collision, the inertia mechanism instantly locks to ensure occupant restraint and safety. The first option is incorrect because the retractor does not remain always locked, allowing the necessary slack for the driver's normal movement. The second option is incorrect because the pre-tensioner is an automatic activation system in case of impact, not manually adjusted by the driver.
