The correct answer is (B) False cause.
Step-by-step explanation:
False cause fallacy, also known as the questionable cause, occurs as one event is attributed to be the cause of another without evidence of it, and only based on the fact the events occurred at the same time or one event was followed by the second event.
This fallacy occurs in the argument presented because the fact that five members contracted diabetes is attributed to the fact Allison is the president of the Retirement Club; however, there is no evidence or proof of a connection between these two events, and it is likely the increase in members with diabetes has a different cause.
