Yes I know the answer maybe if you actually ask the question
Based on the given excerpt, the most logical answer would be C. "To respond to the counterclaim that veganism is bad for the environment."
The information cited clearly shows that the writer is against the consumption of meat. Choices A and D are more like personal attacks on those of the opposing side of the issue, which is inappropriate during an argumentative essay. Choice B is also invalid since the statistics provided don't mention anything related to an individual's personal health.
Situational irony occurs when incongruity appears between expectations of something to happen, and what actually happens instead. From the choices above, I think the correct answer from the choices listed is option D, Ram is trying to be friendly in spite of hostile treatment.
