Explanation

Cloud SQL for MySQL external replica allows you to create a fully managed Cloud SQL instance that acts as a read replica of your on-premises MySQL source. This scales reads and offloads management overhead to Google Cloud without requiring you to manage the replica infrastructure yourself. External server replication (A) refers to replicating FROM an external source INTO Cloud SQL - which is a migration pattern, not an ongoing replica for scaling reads. Data Migration Service (B) is a one-time migration tool, not a long-term replica solution. The mysqldump utility with binary logs (D) can set up replication manually but requires significant manual management and is not the recommended approach.
