You are building an application that will run in your data center. The application will use Google Cloud Platform (GCP) services like AutoML. You created a service account that has appropriate access to AutoML. You need to enable authentication to the APIs from your on-premises environment. What should you do?

A. Use service account credentials in your on-premises application. B. Use gcloud to create a key file for the service account that has appropriate permissions. C. Set up direct interconnect between your data center and Google Cloud Platform to enable authentication for your on-premises applications. D. Go to the IAM & admin console, grant a user account permissions similar to the service account permissions, and use this user account for authentication from your data center.
