Asynchronous automatic failover is incorrect because automatic failover requires replicas to be in synchronous-commit mode, and asynchronous commit allows for potential data loss, which is undesirable if network conditions support synchronous commit.

Synchronous manual failover is not optimal because, while synchronous commit is appropriate, manual failover introduces unnecessary downtime and administrative overhead when automatic failover is achievable and provides higher availability.

Asynchronous manual failover is the least desirable option as asynchronous commit allows for data loss, and manual failover further increases downtime, neither of which is necessary given the low network latency.

Synchronous automatic failover is recommended because the crucial network latency of less than 10 ms allows for synchronous commit mode, which prevents data loss during failover. Automatic failover, which requires synchronous commit, ensures the highest availability by transitioning to a secondary replica without manual intervention.
