  aurora cluster turn on multi az by default. for limit downtime, we create a new read instance. When an update window in the primary instance, the read instance become a new primary instance

  For me option C is the correct!

  C. Turn on the Multi-AZ option on the Aurora cluster. Update the application to use the Aurora cluster endpoint for write operations. Update the Aurora cluster’s reader endpoint for reads. Enabling Multi-AZ ensures that the data in the Aurora cluster is replicated across multiple Availability Zones (AZs), providing high availability and durability. During maintenance, the update will be applied to one AZ at a time, allowing the cluster to remain available. Updating the application to use the cluster endpoint for write operations ensures that writes will continue to be directed to the primary instance in the cluster, while updating the reader endpoint for reads allows read traffic to be routed to the appropriate instance. Adding a reader instance or creating a custom ANY endpoint are not necessary for meeting the requirement of minimizing interruption during maintenance.
