   A team is troubleshooting a terraform plan that fails with the error: "Error: Your query returned no results. Please change your search criteria and try again." The data source is an aws_subnet with a filter on a tag that was recently added to the subnet. What is the most likely cause?

   • AThe subnet was created after the data source was first read, and the state file has not been refreshed.
   • BThe tag filter is case-sensitive and the value in the configuration does not match the tag value exactly.
   • CThe tag was applied to the subnet after the last terraform apply, and the data source query is executed against the live API, which returns no matching subnet.
   • DThe provider configuration is missing the region where the subnet exists.
