You are managing resources in a Google Cloud project.

The correct answer is B because the task is not asking you to invoke the Cloud Run service yourself; it asks for permission to manage IAM policy related to service accounts so the new service account can be granted the required access. The roles/run.invoker role would allow a principal to invoke a Cloud Run service, but it would not give your user permission to modify service account IAM policies. Editor and Owner are excessive and violate least privilege because they grant broad project-level permissions. The roles/iam.serviceAccountAdmin role is the most appropriate option listed because it provides administrative control over service accounts, including managing their configuration and IAM-related access without granting full project ownership.
