Correct A The question refer to prerequisites : When appropriate, before unmounting datastores, make sure that the following prerequisites are met: *No virtual machines reside on the datastore. *Storage DRS does not manage the datastore. *Storage I/O Control is disabled for this datastore. Regarding HA Heartbeating: vSphere HA Heartbeating does not prevent you from unmounting the datastore In our case the VM are powred off, so it will not prevent us from unmounting the datastore: https://geek-university.com/vmware-esxi/remove-vmfs-datastore/ The Main REF https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.storage.doc/GUID-1B56EF97-F60E-4F21-82A7-8F2A7294604D.html

from the link that you provide: Note: Make sure that the datastore is not used by vSphere HA Heartbeating ... before unmounting datastores, make sure that the following prerequisites are met: No virtual machines reside on the datastore. Storage DRS does not manage the datastore. Storage I/O Control is disabled for this datastore.

B is not correct, key word here is "used by" - it would be ok if it was "used for". Correct answer is A
