Agree D is correct - Information from vSAN Deploy and Manage eBook: If an unhealthy disk belongs to a deduplication-enabled diskgroup, the whole diskgroup is marked as unhealthy.

D is the correct answer. Unhealthy disks or diskgroups are marked as such, and at this point, the disks or diskgroups are no longer used for new data placement. If an unhealthy disk belongs to a deduplication-enabled diskgroup, the whole diskgroup is marked as unhealthy.
