Your team has just deployed a new version of an application on Google App Engine. Shortly after the deployment, a critical bug was discovered in this latest release. To mitigate any potential damage and restore the application's functionality, you need to urgently roll back to the previous, stable version of the application. What actions should you take to revert to the prior version of the application?
A
Run gcloud app restore.
B
On the App Engine page of the GCP Console, select the application that needs to be reverted and click Revert.
C
On the App Engine Versions page of the GCP Console, route 100% of the traffic to the previous version.
D
Deploy the original version as a separate application. Then go to App Engine settings and split traffic between applications so that the original version serves 100% of the requests.
