The question stem says 'most similar' and I tend to read that literally. The dominant form of reasoning in the argument is a generalized critique which is best mirrored in C. The other ACs not having a conditional do not mirror the dominant form of reasoning strongly enough to warrant consideration.

Hi! Logic games is indeed off the test. Focus only on Logical Reasoning and Reading Comprehension + the Writing Section (Although that is far less important)

In my understanding, it's not about the order; the major premise supports ONLY the main conclusion and NOT the sub-conclusion
