failed
comforted
succeeded
stood by
Answer is Right!
Answer is Wrong!
The correct answer is A. failed.
To let someone down means to fail to meet their expectations or to fail to do what they need or want you to do. In this case, the friends failed to support the person when they needed them the most.
B. comforted is incorrect because it means to make someone feel better when they are sad or upset. The friends did not make the person feel better, they made them feel worse.
C. succeeded is incorrect because it means to achieve something that you have been trying to do. The friends did not achieve anything, they failed the person.
D. stood by is incorrect because it means to stay with someone or support them during a difficult time. The friends did not stay with the person or support them, they let them down.
