Answer:
None of the choices are correct.
Explanation:
- During their conversation, Curley's wife talks to Lennie about how unsatisfied she is.
- George would not have left Lennie alone if he thought he was going to kill someone.
- Curley's wife is unkind, but at no point during their conversation does she try to kill Lennie.
Thus, the only possible answer is "None of the choices are correct."
