Restoring access (if possible) will give access to the data. Other solutions may result in data inaccessibility.

Selected Answer: C
Restoring access to the witness host will enable the missing components to be accessible. A new witness will not have any metadata for these objects.

i go with c. the witness is offline, not crashed. this means the voting for the vmdk is lost which result in inaccessible vmdks. bring the witness back online

C is Correct. the vSAN Witness Host offline and 2 failures in the Preferred Site. In each of the above failure cases, restoring access to the existing vSAN Witness would make the object accessible. ... Deploying a new vSAN Witness would not because the components would not be present. https://core.vmware.com/resource/vsan-stretched-cluster-guide#sec7373-sub5

C is correct as if you deploy a new Witness host it doesn't have witness Metadata for the object(workloads) impacted in disk group failure. the best approach is to restore the access to existing Witness host

But if the witness site is offline, how can you restore access to it? You shouldn't deploy a new witness to continue working with the secondary site?
