Correct answer & explanation
✓
Grant permissions to a SAML or SCIM group
Options A, B, and C are correct. Lake Formation can grant permissions directly to IAM users/roles (C), to SAML/SCIM groups (A), and via tag-based access control using LF-Tags (B). Option D is incorrect because AWS Organizations units manage accounts, not individual permissions. Option E is incorrect because S3 bucket policies are separate from Lake Formation and cannot be used to grant Lake Formation permissions.
