The answer would be B. She is a female Hercules; she has superior strength.
An allusion is essentially when an author makes some kind of reference to something that isn't really "part" of the text. By this I mean that the author is referencing to something historical or literature. Like in this sentence the author references Hercules. Hercules is from mythology. A easier way to think about this is linking it to real life. A lot of times teenagers "quote" or reference their favorite songs/TV shows/ movies/books in daily conversation. In this situation the teenager is making an allusion.
Hope this made sense!
