For example: Development and test: Azure Stack Hub VMs enable you to create a computer with a specific configuration required to code and test an application. Applications in the cloud: Because demand for your application can fluctuate, it might make economic sense to run it on a VM in Azure Stack Hub. You pay for extra VMs when you need them and shut them down when you don't." Answer is D
