Which statement about the three response actions of an elicitation is correct?

選択肢

1. In URL mode, accept means the out-of-band interaction has completed.
2. Accept and decline both carry the submitted content, and cancel is only used when the client itself fails to render the dialog, which is why the specification tells servers to retry a canceled elicitation immediately rather than treating it as a user decision.
3. Accept means the user approved and submitted, decline means the user explicitly refused, and cancel means the user dismissed without choosing.
4. There are only two actions, accept and reject.
