Answer:
C. Teenagers that play video games are socially awkward.
Step-by-step explanation:
Answer choices A and D agree with the author's points in the passage. Answer choice B is part of the concession the author makes as a writing technique, but answer choice C clearly goes against the message the author is conveying in the passage. The overall point the author is trying to get across is that video games actually make people more social, which is exactly the opposite of answer choice C and therefore they conflict with each other. Thus, C. Teenagers that play video games are socially awkward. is the answer.
