Answer: Use Amazon S3 with Lifecycle policies to transition logs older than one month to a cost-efficient storage solution.
The correct answer is B. Amazon S3 with Lifecycle policies is the most cost-effective solution for this scenario. By storing the logs in Amazon S3 and using S3 Lifecycle policies, the company can automatically transition logs older than one month to S3 Glacier Deep Archive, which is a much cheaper storage option for infrequently accessed data. AWS Backup and CloudWatch Logs are not as cost-effective or practical for handling such a large volume of infrequently accessed data.
