Cloud Spanner is the ideal choice for this scenario because: Global scalability and low latency: Cloud Spanner is designed for globally distributed applications and ensures consistency across multiple regions with minimal latency. Relational schema: It supports relational schemas and SQL queries, making it suitable for applications requiring traditional relational database structures. High availability: Multi-region instances provide automatic failover and data replication for reliability and disaster recovery. Placing compute resources close to the default leader region minimizes latency for write operations, ensuring optimal performance for transactions.

B. The clues are "globally" and "relational schema". Relational rules out Firestore (A) and Bigtable (D). Cloud Spanner is both global in scale and relational, so it fits. So B.

Selected Answer: B
Spanner seems to be the only option, since it's the only relational DB. Plus "scale easily", which is another clear indication of Spanner.
