Hi pokermax3! Here is how I approached this problem:

1st: I recognized that this was a weakening question, the question stem is just worded in an uncommon way.

2nd: I identified the core:

Evidence: Country Classic is the only kind in its class with an antilock braking system with TrackAid.
Conclusion: If you want to buy a car in this class and you are safety-conscious --> the Country Classic (CC) is the only car for you.

3rd: I made note of the flaws that I noticed:

I. Even though TrackAid might be a safety benefit, what if the other cars in CC's class have many other significant safety benefits that CC doesn't have?
II. Also, the other cars in CC class may not have TrackAid, but maybe they have a different system that performs the same function as TrackAid.

4th: I approached the answer choices looking for a weakener, ideally one that touches on either of the flaws mentioned above:

(A) No. This doesn't prove that the other cars might be as safe or safer than CC. This just qualifies the other cars in CC's class: like CC, they all have an antilock breaking system. Yet we already know they don't have the TrackAid.
(B) No. The same manufacturer doesn't prove anything about safety.
(C) No. We don't know whether or not the other cars have an antilock braking system, so this cannot do anything to the argument.
(D) Yes. This addresses Flaw II. If the other cars in CC's class offer an antilock break system that uses a different method to achieve the same result as TrackAid, then this calls into question about CC being the safest car in the group. With (D) being true, we don't know any safety differences between CC and the other cars in its class.
(E) No. Expense is irrelevant to safety for this argument.

Hope this helps!
