difference between b and c?

Could you clarify why B is the correct answer? Thank you

@AllieC and @Ella-Singh, Happy to help. Let's take a look at (B) and (C). (C) says, "He failed to take into consideration the discrepancy in numbers between favorable and unfavorable letters received." Because the decision the programming director is making is about keeping the movie review segment, the number of favorable reviews about all of the other segments—including news and music—is irrelevant. Thus, (C) doesn't identify a real problem, so it's out. (B) says, "He could not properly infer from the fact that some listeners did not like the movie review segment that some others did." (B) provides an accurate description of the programming director's faulty inference. We don't know what other listeners were thinking based on the fact that there were ten unfavorable reviews. It's possible that everybody hated the reviews. We have no clue if anyone liked it. Thus, (B) captures the error in the director's decision process, so it's the correct answer choice. Does this make sense? Let us know if you have any more questions!
