Answer:
Her mistaken recall best illustrates source amnesia.
Explanation:
Source amnesia can be defined as a memory disorder in which a person is able to recall a factual knowledge, but they distort contextual elements such as where, when, or how they obtained it, or simply cannot recall those elements. This type of amnesia is associated with the malfunctioning of explicit memory. Notice that Margo can remember the horrors portrayed in the movie, but she is unable to recall that she obtained that information from the movie, not from something that truly happened to her.
