No this is controversial in my view, the highlighted text is not saying anything about the response of the audience. It merely repeating itself from the top passage

OE2. The author mentions the mixing of “traditions of moralism with those of comedy” (Highlighted) primarily in order to The second paragraph states that “[t]he opera mixed traditions of moralism with those of comedy—a practice heretofore unknown among the composer’s works—resulting in a production that was not well-liked by conservative Viennese audiences.” The language “a practice heretofore unknown” indicates that Mozart had not done this before. Correct answer (A) is a good match—a “lackluster reception” means that those who “received” something (the audience) were unimpressed. Note that the GRE is trying to hide the correct answer a little bit by saying “a particular group of people” for “Viennese audiences.” Also note that (D) and (E) are incorrect because the author does not “argue” or “undermine” at any point. Talking about moralism and comedy doesn’t address the plot, as mentioned in choice (B), and the passage does not mention what is common in contemporary (modern) opera, so choice (C) is out of scope.
Answer: A
