A vs C

I was stuck between A and C. How can I better eliminate C? it took me too long to go between the two. I chose A but I wasn't confident in it. Is C wrong because less expensive features are not mentioned and we don't know how effective the less expensive features would be? Thanks in advance.

Hi Lerondagates, thanks for the question.

Answer choice C is incorrect because it is saying that the argument presumes that less expensive and equally effective means of reducing pedestrian injuries exist. So I wouldn't say that this is incorrect because we don't know how effective these less expensive features would be, but simply that the flaw described does not apply to the argument, because the argument does not assume this to be true.

I hope this helps, please let me know if you have any other questions.
