What should you do?

You are designing a highly available (HA) Cloud SQL for PostgreSQL instance that will be used by 100 databases. Each database contains 80 tables that were migrated from your on-premises environment to Google Cloud. The applications that use these databases are located in multiple regions in the US, and you need to ensure that read and write operations have low latency.

What should you do?
A . Deploy 2 Cloud SQL instances in the us-central1 region with HA enabled, and create read replicas in us-east1 and us-west1.
B . Deploy 2 Cloud SQL instances in the us-central1 region, and create read replicas in us-east1 and us-west1.
C . Deploy 4 Cloud SQL instances in the us-central1 region with HA enabled, and create read replicas
in us-central1, us-east1, and us-west1.
D . Deploy 4 Cloud SQL instances in the us-central1 region, and create read replicas in us-central1, us-east1 and us-west1.
