Answer: A

Explanation:

You can deploy to a different project by using Cproject flag.

By default, the service is deployed the current project configured via:

$ gcloud config set core/project PROJECT

To override this value for a single deployment, use the Cproject flag:

$ gcloud app deploy ~/my_app/app.yaml Cproject=PROJECT
