Step-by-step explanation:
The symbolic meaning of Moses' staff turning into a snake and consuming the snakes of Pharaoh's assistants is primarily A. Victory of God's power over evil. This act demonstrated the supremacy of Moses' God over the Egyptian magicians and their deities, reinforcing the central theme of the Exodus story: the power of the Hebrew God and His protection and guidance of the Israelites. The staff turning into a snake and defeating the other snakes can also be seen as a prediction of the eventual defeat of Pharaoh, symbolically represented by the snakes of his assistants, cementing the power and authority of the God of Israel in the narrative.
