Answer: Enable Multi-AZ deployment.
The correct answer is A: Enable Multi-AZ deployment. This solution ensures high availability and automatic failover, which supports the requirement of a recovery point objective (RPO) of less than 1 second. Multi-AZ deployments automatically replicate the database to a standby instance in another Availability Zone and provide enhanced durability and availability of the RDS database instance. Other options do not guarantee the desired RPO with the same level of reliability.
