Automobile Dealer's Advertisement:  
The Highway Traffic Safety Institute reports that the PZ 1000 has the fewest injuries per accident of any car in its class.  This shows that the PZ 1000 is one of the safest cars available today.  Which of the following, if true, most seriously weakens the argument in the advertisement?  
(A) The Highway Traffic Safety Institute report listed many cars in other classes that had more injuries per accident than did the PZ 1000.
(B) In recent years many more PZ 1000s have been sold than have any other kind of car in its class.
(C) Cars in the class to which the PZ 1000 belongs are more likely to be involved in accidents than are other types of cars.
(D) The difference between the number of injuries per accident for the PZ 1000 and that for other cars in its class is quite pronounced.
(E) The Highway Traffic Safety Institute issues reports only once a year.  

这题怎么就C了 C上说的也是PZ1000所在class里其他的车系 不代表否定了PZ1000啊 为什么就C了 = =
