Choice B is the best answer because it most logically completes the discussion of Octavia Butler’s career. In this context, “impenetrable” means impossible to enter. The text indicates that the field of science fiction was dominated by white males when Butler, a Black woman, started writing, but she published several science fiction short stories and a novel and later won a prestigious award; that is, Butler pursued science fiction writing and had success. This context suggests that Butler didn’t view the genre as impossible to enter. 
Choice A is incorrect. In this context, “legitimate” would mean genuinely good or valid. Nothing in the text suggests that Butler didn’t think the science fiction genre was good or valid; in fact, it indicates that she pursued and made a successful career of publishing work in that field. Choice C is incorrect. In this context, “compelling” would mean attracting or demanding attention. The text indicates that Butler chose to write science fiction, so it wouldn’t make sense to say that she didn’t see the field as drawing her attention. Choice D is incorrect. To say that Butler didn’t consider science fiction “indecipherable,” or impossible to understand, would suggest that Butler did understand it. However, the text doesn’t address Butler’s ability to interpret works in the genre; rather, it focuses on Butler’s successful pursuit of writing science fiction.
