Answer: C

Explanation:

The module twin for the IoT Edge agent is called $edgeAgent and coordinates the communications between the IoT Edge agent running on a device and IoT Hub. The desired properties are set when applying a deployment manifest on a specific device as part of a single-device or at-scale deployment.

These properties include:

– runtime.settings.registryCredentials.{registryId}.username

– runtime.settings.registryCredentials.registryId}.password
