Final answer:
The wasp Rostropria garbo was not named for reasons related to Greta Garbo's resemblance, behavior, discoveries, or acting roles. The reference to a butterfly's long-distance migration could imply a metaphorical tribute in naming the wasp, though the context does not confirm this. The butterfly's migration trait is a genetically inherited survival mechanism. The correct option is b.
Step-by-step explanation:
The wasp Rostropria garbo was not named after Greta Garbo because it resembles her, behaves like her, she discovered it, or because she acted in a bug movie. However, if we consider the provided reference information about a butterfly inheriting long-distance migration behavior from its ancestor, it suggests that the name in question might have been given as an homage to something related to Greta Garbo, such as her ability to captivate audiences over a long distance, similar to how some species inherit remarkable traits like long-distance migration through genetics. Yet, the context provided doesn't directly explain why the wasp is named after Greta Garbo. As for the butterfly and its long-distance migration behavior, this genetic inheritance allows the new species to continue a vital life-cycle pattern established by its forebears, ensuring its survival and reproductive success.
