You Are Integrating One of Your Internal IT Applications and Google

You are integrating one of your internal IT applications and Google BigQuery, so users can query BigQuery from the application's interface. You do not want individual users to authenticate to BigQuery and you do not want to give them access to the dataset. You need to securely access BigQuery from your IT application. What should you do?

A) Create groups for your users and give those groups access to the dataset
B) Integrate with a single sign-on (SSO) platform, and pass each user's credentials along with the query request
C) Create a service account and grant dataset access to that account. Use the service account's private key to access the dataset
D) Create a dummy user and grant dataset access to that user. Store the username and password for that user in a file on the files system, and use those credentials to access the BigQuery dataset
