A Company Has Sales Department and Marketing Department

A company has Sales department and Marketing department. The company uses one AWS account. There is a need to determine what charges are incurred on the AWS platform by each department. There is also a need to receive notifications when a specified cost level is approached or exceeded. Which two actions must a SysOps Administrator take to achieve both requirements with the LEAST amount of administrative overhead? (Choose two.)

A) Use AWS Trusted Advisor to obtain a report containing the checked items in the Cost Optimization pillar.
B) Download the detailed billing report, upload it to a database, and match the line items with a list of known resources by department.
C) Create a script by using the AWS CLI to automatically apply tags to existing resources to each department. Schedule the script to run weekly.
D) Use AWS Organizations to create a department Organizational Unit and allow only authorized personnel in each department to create resources.
