In a car, which of the following elements reduces the risk of neck injuries in a collision?

# Explanation: Headrest and Neck Injuries A properly adjusted headrest is the most effective element for reducing neck injuries during a collision. Its function is to limit the backward movement of the head, preventing the "whiplash" that occurs when the head is violently thrown backwards. Although the seat belt and ABS brakes are important for overall safety, they are not specifically designed to protect the neck in impacts.
