Answer: C) It deflects human responsibility by portraying the bank as the villain.
Step-by-step explanation: A metaphor is an indirect comparison between elements that don't are related in an obvious way, it is often used to create an image that helps to explain a point of view or an idea. In the given excerpt from "The Grapes of Wrath" by John Steinbeck, we can see a metaphor that compares the bank with a monster, it says that men created the bank but now they can't control it, so this metaphor helps to deflect human responsibility by portraying the bank as the villain.
