Suggested Answer:C🗳️
The vSAN components that reside on the magnetic disk or flash capacity device are marked as degraded. Reference: https://docs.vmware.com/en/VMware-vSphere/6.5/com.vmware.vsphere.virtualsan.doc/GUID-9A2DCE0B-CFA1-41C1-97CE-DA56A55426EA.html
For those confused between C and D and have every right to be as usch F** question, this KB should point to C being correct
https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.vsan-monitoring.doc/GUID-9A2DCE0B-CFA1-41C1-97CE-DA56A55426EA.html
C is right
vSAN components are found in a variety of states:
• Active components: Healthy and functioning correctly.
• Reconfiguring components: In the process of applying storage policy changes.
• Absent components: No longer available due to a failure.
• Stale components: No longer in sync with other components of the same vSAN object.
• Degraded components: Not expected to return due to a detected failure.
So, absent appears when a Maintenance operation is done in the vSAN cluster
Another bad question. Inaccessible can be absent or degraded. See the VMware article below.

D is correct answer
capacity disk inacesible means disk was removed from host and VSAN believes that component re-appear )
https://cormachogan.com/2014/12/04/vsan-part-30-difference-between-absent-degraded-components/
Absent means that the component is still there, it will be back later but not gone away.
A component is in absent state if vSAN detects a temporary component failure where the component might recover and restore its working state.
So answer is C, degraded.
vSAN examines whether the hosts and the capacity devices can satisfy the requirements for space and placement rules for the objects on the failed device or disk group. If such a host with capacity is available, vSAN starts the recovery process immediately because the components are marked as degraded.
