Answer: Apply an S3 lifecycle policy to move files to S3 Standard-Infrequent Access after 30 days and delete after 4 years.
The correct answer is C. Creating an S3 bucket lifecycle policy to move files from S3 Standard to S3 Standard-Infrequent Access (S3 Standard-IA) after 30 days is the most cost-effective solution, given that the files are rarely accessed after the first 30 days. S3 Standard-IA provides lower storage costs for infrequently accessed data while still offering the immediate accessibility required by the company. Deleting the files after 4 years complies with the company's data retention policy.
