Your organization has an existing app that just went viral. The app uses a Cloud SQL for MySQL backend database that is experiencing slow disk performance while using hard disk drives (HDDs). You need to improve performance and reduce disk I/O wait times. What should you do?

A. Export the data from the existing instance, and import the data into a new instance with solid-state drives (SSDs). B. Edit the instance to change the storage type from HDD to SSD. C. Create a high availability (HA) failover instance with SSDs, and perform a failover to the new instance. D. Create a read replica of the instance with SSDs, and perform a failover to the new instance
