   A logistics company has a mobile app that lets customers track packages. The backend currently uses a single regional Cloud SQL instance and a Compute Engine VM running a REST API. The company expects to expand to two new countries in the next year, and customers in those regions will need low-latency access. What architectural change best prepares the system for this growth?

   • ADeploy the API to Cloud Run in multiple regions and use a global external load balancer with Cloud SQL read replicas in each region.
   • BUse Cloud CDN to cache API responses and keep the existing single-region backend.
   • CMigrate the database to Cloud Spanner and deploy the API to Compute Engine in a single region.
   • DKeep the single-region deployment but increase the VM's machine type and Cloud SQL storage to handle the additional traffic.
