Whenever a major airplane accident occurs, there is a dramatic increase in the number of airplane mishaps reported, a phenomenon that may last for as long as a few months after the accident. Airline officials assert that the publicity given the gruesomeness of major airplane accidents focuses media attention on the airline industry and the increase in the number of reported accidents is caused by an increase in the number of news sources covering airline accident, not by an increase in the number of accidents. Which of the following, if true, would seriously weaken the assertions of the airline officials? (A) The publicity surrounding airline accidents is largely limited to the country in which the crash occurred. (B) Airline accidents tend to occur far more often during certain peak travel months. (C) News organizations do not have any guidelines to help them decide how severe or how close an accident must be for it to receive coverage. (D) Airplane accidents receive coverage by news sources only when the news sources find it advantageous to do so. (E) Studies by government regulations show that the number of airplane flight miles remains relatively constant from month to month.
The best answer given is B. Can anyone please explain how B is better than C? I think C is better as it states that news organizations can report any airline accident irrespective of when it occured or how severe accident is.

Premise: Major airline accident --> Increase in airplane mishaps for next few months. Assertion: Number of accidents reported increases due to increased coverage not due to actual increase in the number of accidents.
We have to weaken the assertion. The assertion assumes that the actual number of accidents doesn't increase.
B. Airline accidents occur often during certain months - this indicates a NEW cause for the rise in reported mishaps, and weakens the assertion that the cause is increased coverage.
C. This only tells us they don't have any guidelines. It also says it generally, and thus this would be true for whether or not the number of accidents has actually increased. Does it tell us that they are reporting more accidents than before, or give us a new cause for the increase? No.
