The correct answer is E When creating an image maybe you are restricted to a region but you can replicate the image to other regions later See step 16 from "Create an image" in this article : https://learn.microsoft.com/en-us/azure/virtual-machines/image-version?tabs=portal%2Ccli2#create-an-image which states that: "In Region, select the region where you want the image created. In some cases, the source must be in the same region where the image is created. If you aren't seeing your source listed in later drop-downs, try changing the region for the image. You can always replicate the image to other regions later."

Note from MS documentation: Depending on the image you choose, the Region the VM will be created in will change to match the image. https://learn.microsoft.com/en-us/azure/virtual-machines/vm-specialized-image-version?tabs=cli%2Cportal2

Azure Compute Gallery - formerly known as Shared Image Gallery - lets you share your custom VM images with others in your organization, within or across regions, within a Microsoft Entra tenant, or publicly using a community gallery. Choose which images you want to share, which regions you want to make them available in, and who you want to share them with. https://learn.microsoft.com/en-us/azure/virtual-machines/image-version?tabs=portal%2Ccli2

Additionally: "Batch only supports generalized Shared Images; a specialized Shared Image can't be used to create a pool." https://learn.microsoft.com/en-us/azure/batch/batch-sig-images
