Answer options:

Answer – D 
This is an example of having infrastructure hosted in both the Azure public cloud and your on-premises network. 
Option A is incorrect since the picture shows that the "on-premises" network ( left side of the image ) is establishing a connection to the Azure virtual network ( right side of the image ). 
Option B is incorrect since there is an on-premises server on the left-hand side. 
Option C is incorrect since there is no specification of a pure government cloud setup.
