OG-verbal review Q24 might qualify under "Incorrect comparison type"

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 recently years many more PZ 1000's 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
54 class is quite pronounced.
(E) The Highway Traffic Safety Institute issues reports only once a year.

In this Ques, PZ1000, which has fewest inj/acci in it's class, is declared as one of the safest cars today. The argument "incorrectly" compares PZ1000 to all cars available today

For the "Qualified conclusion" type, I'm not too sure but Q50 (discussed here) in Verbal review seems like a match.
In this Ques, the author concludes that adequate moisture is essential for crop's survival and will result in prices falling sharply. This conclusion leaves the argument to attack with alternate causes, which may impact the crop's survival.
