Selected Answer: A

Significant performance improvement: AlloyDB delivers this for PostgreSQL workloads. Minimizing changes to data schema and application code: AlloyDB is PostgreSQL-compatible, making this the best option. Spanner, Firebase, and Bigtable would all require substantial changes. Exceed 150 TB of data per geographical region: AlloyDB is designed for large-scale enterprise workloads and can scale. While Spanner and Bigtable can handle this more easily, they fail on the schema/code change requirement. Google-recommended practices: AlloyDB is Google's flagship PostgreSQL-compatible service. Minimize operational costs: As a fully managed service, AlloyDB reduces operational overhead.
