A company wants to migrate its SAP S/4HANA infrastructure to AWS. The infrastructure includes production, pre-production, test, and development environments. The pre-production environment is an identical copy of the production environment. The production system must comply with a new policy that requires the landscape to be able to fail over to a secondary AWS Region. The required RPO is 5 minutes. The required RTO is 4 hours. The estimated SAP HANA database size is 6 TB. Which solution will meet these requirements MOST cost-effectively?

A. Deploy the pre-production environment in a primary Region. Deploy the other environments in a secondary Region. Configure the disaster recovery SAP HANA system on the pre-production hardware. Implement replication by setting the preload_column_tables parameter to false. Before failover, stop the pre-production environment, set the preload_column_tables parameter to true, and allocate the memory for production takeover.
B. Deploy all environments in a primary Region. Configure a 500 GB disaster recovery (DR) site in a secondary Region. Configure DR SAP HANA system replication on the pre-production hardware by setting the preload_column_tables parameter to false. In the event of a disaster, resize the DR environment to 6 TB, set the preload_column_tables parameter to true, and perform a takeover.
C. Deploy all environments in a primary Region. Configure a 6 TB disaster recovery (DR) site in a secondary Region. In the event of a disaster, perform a takeover on the DR site.
D. Deploy all environments in a primary Region. Configure a 6 TB disaster recovery (DR) site in the same Region. In the event of a disaster, perform a takeover on the DR site.
