   Contoso Pharmaceuticals runs a legacy patient-records application on a dedicated on-premises server cluster. Regulatory requirements mandate that patient data remain within the country, but the application's compute load spikes unpredictably during flu season. Contoso wants to use Microsoft 365 and Azure to handle the spikes without replacing the legacy application. Which approach best meets the requirements while minimizing long-term cost?

   • AKeep the application on-premises and use Azure for burst capacity, connecting the environments with a site-to-site VPN and replicating only the data needed for the burst.
   • BMove the application to a private cloud hosted by a third-party provider in the same country, with no connection to the existing on-premises systems.
   • CMigrate the entire application and all patient data to Azure public cloud in a single region within the country.
   • DKeep everything on-premises and purchase additional servers to handle the seasonal peak demand.
