Answer: A

Explanation:

"Your key vault and VMs must be in the same subscription. Also, to ensure that encryption secrets don’t cross regional boundaries, Azure Disk Encryption requires the Key Vault and the VMs to be co-located in the same region." https://docs.microsoft.com/en-us/azure/virtual-machines/windows/disk-encryption-key-vault
