OG12-78实在想不透

A recent report determined that although only 3 percent of drivers on Maryland highways equipped
their vehicles with radar detectors, 33 percent of all vehicles ticketed for exceeding the speed limit were
equipped with them. Clearly, drivers who equip their vehicles with radar detectors are more likely to exceed
the speed limit regularly than are drivers who do not.
The conclusion drawn above depends on which of the
following assumptions?

(A) Drivers who equip their vehicles with radar detectors are less likely to be ticketed for
exceeding the speed limit than are drivers who do not.
(B) Drivers who are ticketed for exceeding the speed limit are more likely to exceed the speed
limit regularly than are drivers who are not ticketed.
(C) The number of vehicles that were ticketed for exceeding the speed limit was greater than the
number of vehicles that were equipped with radar detectors.
(D) Many of the vehicles that were ticketed for exceeding the speed limit were ticketed more
than once in the time period covered by the report.
(E) Drivers on Maryland highways exceeded the speed limit more often than did drivers on other
state highways not covered in the report.

b选项如何充当条件的？？怎么个道理呢？
