The answer list is not correct. we need to have a custom role for this task. BTW, Option C (assigning the Cloud Spanner Database User role) does not provide the necessary permissions to add columns and indexes or perform DDL operations. that said, it not correct either :)

C. This has nothing to do with backups. Eliminate A. Any admin role would be too wide. Eliminate B and D. That leaves C. roles/spanner.databaseUser provides r/w. view and update schemas. https://cloud.google.com/spanner/docs/iam#spanner.databaseUser
