Which of the following investigations is most likely to expose a logical flaw in the above hypothesis?
A) Comparing the number of fatalities seperately for drivers and for pedestrians
B) Comparing the number of casualties in each group per 1,000 people, instead of the total number of casualties
C) Comparing the number of fatalities in Californian motorcycle accidents to the number of fatalities in motorcycle accidents nationwide
D) Calculating the ratio between the fatality totals in both groups
