Answer options:

A.Resource Groups
B.Management Groups
C.Azure Policies
D.Azure App Service

Answer – B 
The correct answer is B, Management Groups. From the Microsoft Documentation, Azure Management Groups are containers for managing access across multiple Azure subscriptions. 

Option A is invalid because this is good for grouping your resources together.
Option C is incorrect because Azure Policies are valid only within one subscription.
Option D is invalid because this is used to host your web applications.
