Which is NOT true of anecdotal stories?

A. They are strongly supported by facts

B. They are based on personal experience

C. They cannot be proven

D. They are the main source of information in cryptozoology

Anecdotes are stories from the past, a part of someone's personal experience which is why they have to be factual if they are to be truthful. They can usually be checked, so i would say the correct answer is D. They are the main source of information in cryptozoology, since the main source is actually folklore, not anecdotes.
