Correct answer is A. Cloud SQL is a fully-managed relational database service that supports MySQL, PostgreSQL, and SQL Server. It offers high availability, automatic backups, and point-in-time recovery. By enabling binary logging, you can restore your database to a specific point in time. Cloud SQL is a cost-effective solution for small sets of operational data in one geographic location. It is also a good choice for developers who are familiar with MySQL.

Perform the point-in-time recovery using binary log positions
While we recommend you perform point-in-time recovery using timestamps as described in the previous procedure, you can also perform point-in-time recovery by providing a specific binary log position in a binary log file.
