Answer: Amazon RDS Multi-AZ (Availability Zone)
Option B, Amazon RDS Multi-AZ, is the correct answer. Amazon RDS Multi-AZ provides high availability and fault tolerance by automatically replicating your database to a standby instance in a different Availability Zone. In the event of a failure, Amazon RDS can automatically failover to the standby instance, ensuring minimal downtime and data loss. While options A, C, and D offer various high availability and fault tolerance capabilities, they do not provide the same level of database-specific high availability as Amazon RDS Multi-AZ.
