Answer: A

Explanation:

Device Twins are used to synchronize state between an IoT solution’s cloud service and its devices. Each device’s twin exposes a set of desired properties and reported properties. The cloud service populates the desired properties with values it wishes to send to the device. When a device connects it requests and/or subscribes for its desired properties and acts on them.
