Which of the following is an assumption underlying the reasoning in the passage above?
A In most fatal automobile accidents , the driver of a car in which an occupant is killed is at fault .
B Most deaths in fatal automobile accidents are suffered by occupants of cars rather then by pedestrians .
C Auto safety experts should increase their efforts to provide protection for those in the passenger seats of automobiles
D Automobile passengers sometimes play a contributing role in causing auto accidents
