A client stores the access token it received and reuses it. Which pair of facts about that token is correct?

選択肢

1. The token stays valid for sixty minutes, and the response reports the same validity so that a replacement can be requested at the end.
2. The token stays valid until it is revoked, and the response reports no validity so that a replacement can be requested at any time.
3. The token stays valid for twenty minutes, and the response reports a shorter validity so a replacement is requested early.
4. The token stays valid for twenty minutes, and the response reports a longer validity so that a replacement can be requested after the end.
