Correct answer & explanation
aws rds describe-db-instances: Retrieves details about RDS DB instances
The correct matches pair each AWS CLI command with its corresponding database service. Common confusions involve swapping commands between RDS, DynamoDB, Redshift, and ElastiCache. Remember that each service has its own command namespace (e.g., 'aws rds', 'aws dynamodb', 'aws redshift', 'aws elasticache').
