Answer: S3 Standard with Lifecycle policy to S3 Standard-IA after 30 days, then to S3 Glacier Deep Archive after 1 year.
Option D is the correct answer. Using the S3 Standard storage class initially ensures that the data is available with minimal delay for up to 30 days. Creating an S3 Lifecycle policy to transition the objects to S3 Standard-Infrequent Access (S3 Standard-IA) after 30 days significantly reduces storage costs while still providing prompt access needed for quarterly analysis. Finally, transitioning to S3 Glacier Deep Archive after 1 year ensures very cost-effective long-term archival storage. This setup balances both performance and cost requirements effectively.
