The correct answer is C. 45
Step-by-step explanation:
Lap/shoulders safety belts are essential to reduce the risk of injuries and death during car accidents because they keep passengers in the seat and avoid ejection, which might lead to more serious injuries. This has been widely studied around the world, including studies by the National Center for Statistics and Analysis in the U.S. that determined safety belts decrease the risk of serious or fatal injuries by 45%. Also, similar results were reported in other research studies that collected information about accident cars, the injuries passengers suffered, and whether the front-seat passengers had a safety belt on.
