Suggested Answer: BD 🗳️
The IoT Hub resource logs connections category emits operations and errors having to do with device connections. The following screenshot shows a diagnostic setting to route these logs to a Log Analytics workspace:

Note: Azure Monitor: Route connection events to logs:
IoT hub continuously emits resource logs for several categories of operations. To collect this log data, though, you need to create a diagnostic setting to route it to a destination where it can be analyzed or archived. One such destination is Azure Monitor Logs via a Log Analytics workspace, where you can analyze the data using Kusto queries.

Answers are correct. D is clear, see reference. C and E are basically nonsense, can be discarded. A is a valid option for trouble-shooting, but not with Azure Monitor. It is for offline analysis, ref. https://docs.microsoft.com/en-us/azure/iot-hub/monitor-iot-hub
