You are in the process of developing a financial trading application that will have a global user base. To ensure data integrity and consistency, the data is stored and queried using a relational database structure. It is crucial that all clients, regardless of their location worldwide, access the same, consistent state of the data. The application is to be deployed in multiple geographical regions to minimize latency and enhance user experience. Given these requirements, which storage option should you choose to effectively minimize latency for the application data?

Explanation:
The correct answer is C: Use Cloud Spanner for data storage. Cloud Spanner is a globally distributed, strongly consistent relational database service that provides high availability and low latency. It is specifically designed to handle global applications that require consistent and synchronized data across multiple regions. Other options like Cloud Bigtable, Cloud SQL, and Firestore either do not support a relational structure, strong consistency, or global distribution in the same way Cloud Spanner does.
