Explanation

B: Message enrichments is the ability of the IoT Hub to stamp messages with additional information before the messages are sent to the designated endpoint. One reason to use message enrichments is to include data that can be used to simplify downstream processing. For example, enriching device telemetry messages with a device twin tag can reduce load on customers to make device twin API calls for this information. D: Applying enrichments The messages can come from any data source supported by IoT Hub message routing, including the following examples: -->device twin change notifications --changes in the device twin device telemetry, such as temperature or pressure device life-cycle events, such as when the device is created or deleted https://docs.microsoft.com/en-us/azure/iot-hub/iot-hub-message-enrichments-overview
