"members": ["user:alice@example.com"], "role": "roles/viewer" correctly places the user in "members" and the role in "role" with proper formatting.
Final Answer:
"members": ["user:alice@example.com"], "role": "roles/viewer" -> Option D
Quick Check:
Role = roles/viewer, Members = user list [OK]

Quick Trick: Remember: role is a string, members is a list [OK]
