The most closely related symbol in the passage regarding the raven perched on the bust of Pallas Athena is:
C. That nature powers over the strongest of human knowledge.
The image of the raven, a symbol often associated with omens and death, sitting on the bust of the goddess of wisdom (Pallas Athena) suggests a contrast between the dark, chaotic presence of the raven and the ideal of knowledge and wisdom that Athena represents. This contrast can symbolize the idea that even in the presence of human knowledge and enlightenment, darker forces or nature can impose their influence.
