Answer: Select Cloud Spanner.
Given the requirements for a mission-critical global payments gateway application that must be available 24/7, horizontally scalable, support open source databases, be automatically shardable, fully managed, offer 99.999% availability, and strong transactional consistency, the best option is Cloud Spanner. Cloud Spanner is a globally distributed database service that provides high availability, horizontal scalability, and strong consistency across regions. It is fully managed and supports automatic sharding. Bare Metal Solution for Oracle is not fully managed and does not inherently support open source databases. Cloud SQL is not designed for horizontal scalability across regions and does not offer 99.999% availability. Bigtable is a NoSQL database that does not support strong transactional consistency across regions.
