Answer options:

A.Your DB is not using premium storage.
B.You are enabling auditing in a paused Azure Synapse SQL.
C.Enabling auditing should be done during the creation and cannot be changed later.
D.All of the above

Correct Answer: B
Auditing is a very important security feature that helps you track database events and writes. This can be stored in an azure storage account or sent to log analytics.
But in the case of Azure synapse SQL, there are certain limitations that may block you from enabling auditing. 
They are 
->using premium storage 
-> enabling auditing on a paused Azure Synapse 
->support is only for default audit action groups 
If you have to enable auditing in Azure Synapse which is issued, you will have to resume it first.
Option A incorrect: Premium storage is the only unsupported storage option.
Option B is correct: Paused Azure Synapse should be resumed before enabling the auditing feature.
Option C is incorrect: This feature can be changed later as well.
Option D is incorrect: One of them is correct.
