Due to a planned power outage, an administrator decides to shut down the vSAN cluster using the Shutdown Cluster Wizard. The administrator starts by checking the vSAN health service to confirm the cluster is healthy and then powers off all virtual machines (VMs) including vCLS VMs.
Which step needs to be taken before starting the Shutdown Cluster Wizard?
Before starting the Shutdown Cluster Wizard, the administrator needs to turn off High Availability. This prevents the cluster from trying to restart the VMs as part of its high availability functionality when the power outage occurs. Ensuring HA is turned off is crucial to avoid any automated attempts to manage or restart VMs during the shutdown process.

Correct answer is C https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.vsan-monitoring.doc/GUID-31B4F958-30A9-4BEC-819E-32A18A685688.html
In fact, this question is strange : tasks listed in A, B & C are in fact managed by the Shutdown Cluster Wizard. See following link for reference : https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.vsan-monitoring.doc/GUID-89211E74-69A5-4126-AABC-A70984C56A8F.html And of course, if you shutdown the vCenter (Answer D), you cannot access the wizard. The only answer I could see if C, because it is the first task realized by the wizard, and the first one in a manual shutdown.
A. Place all ESXi hosts into maintenance mode Placing hosts into maintenance mode will trigger the vMotion of virtual machines to other hosts in the cluster, ensuring a controlled and graceful evacuation of VMs. This is an essential step to avoid data unavailability or disruption during the cluster shutdown.
the question states that the admin has already powered off the VMs 'and then powers off all virtual machines (VMs) including vCLS VMs' C: is correct, turn off HA
But of the 4 answers, "A" is the most valid. No harm putting ESX into maintenance mode though it is not necessary based on the notes below https://docs.vmware.com/en/VMware-vSphere/8.0/vsan-administration/GUID-0D24C5BA-0248-4E3A-ADA3-33FF551C78F5.html
