Read the excerpt below and answer the question. [Upon learning of Lucy's engagement, the narrator describes Elinor:] Elinor's security sunk; but her self command did not sink with it. What can you infer from the narrator's description?

The answer is the second option: Elinor did not let down her guard.

Explanation:

When the author says: "Elinor's security sunk; but her self command did not sink with it" is stating that even though Elinor felt insecure, she hid it very well to not seem weak. The first option is not correct because the narrator never mentions that Elinor is having a feeling of anger. The third option is not accurate since the excerpt never implies the choosing of an argument. The fourth option is not right because it does not say that Elinor wants to win against Lucy.

B is the right answer
