You manage an Azure subscription with virtual machines (VMs) that are running in Standard mode.
You need to reduce the storage costs associated with the VMs.
What should you do?
A . Locate and remove orphaned disks.
B . Add the VMs to an affinity group.
C . Change VMs to the Basic tier.
D . Delete the VHD container.
Standard offers 50 GB of storage space, while Basic only gives 10 GB but it will save costs.
