Correct answer: A

Explanation

Cost allocation tags must be activated in the AWS Organizations management account to be applied across consolidated billing. Setting up the AWS Cost and Usage Report (CUR) in the management account allows the organization to consolidate billing data from all member accounts into a single Amazon S3 bucket. Querying this data using Amazon Athena and visualizing it via Amazon QuickSight is the standard, recommended serverless architecture for granular cost analysis.
