   A cold-chain logistics company transports vaccines in temperature-controlled containers. The system must log temperature every minute, alert if the temperature deviates by more than 2°C, and provide a compliance report for regulators. The containers travel through areas with intermittent connectivity. The company must choose between storing data locally on the container and transmitting to the cloud in real time. Which design decision best balances the compliance and connectivity constraints?

   • AStore data locally on the container and synchronize to the cloud when connectivity is available
   • BTransmit data to the cloud in real time and rely on the cloud to store all historical data
   • CTransmit data to the cloud only when the container is at a depot with Wi-Fi
   • DStore data locally and never transmit it to the cloud
