You are creating an internal App Engine application that needs to access a user's Google Drive on the user's behalf. Your company does not want to rely on the current user's credentials. It also wants to follow Google-recommended practices.
What should you do?

A. Create a new Service account, and give all application users the role of Service Account User. B. Create a new Service account, and add all application users to a Google Group. Give this group the role of Service Account User. C. Use a dedicated G Suite Admin account, and authenticate the application's operations with these G Suite credentials. D. Create a new service account, and grant it G Suite domain-wide delegation. Have the application use it to impersonate the user.
