The requirements is "real-time" alerts. Therefor the answer is not D. Blob storage is not real-time. A creates a realtime custom endpoint , C uses the realtime default endpoint.

I wonder if answer C can be correct. As there's already a route defined which routes all messages to blob storage, the built-in 'events' endpoint will not receive any messages anymore.

Once a Route is created, data stops flowing to the built-in-endpoint unless a Route is created to that endpoint.

Why should the answer D not be correct ? It is possible to configure Routing to blob storage and also possible to choose the blob as input of the stream analytics. May someone clarify it ?

Ans can't be D, as it adds blob as Reference Input not as Streaming input https://docs.microsoft.com/en-us/azure/stream-analytics/stream-analytics-add-inputs#stream-and-reference-inputs
