An administrator is migrating from a standalone ESXi host and needs to provide access to...

Nutanix documentation and KB guidance for transferring virtual disks to AHV clearly state that when a source hypervisor such as ESXi needs temporary access to a Nutanix storage container, administrators should add the host IP address to the filesystem whitelist. That is the approved mechanism for allowing the source host to mount or access the container for migration purposes. This makes D the correct answer.

The wording “setup as an NFS share” is too generic and is not the exact Nutanix administrative step. Nutanix storage containers are not meant to be treated as open general-purpose file shares. Importing the ESXi host into AHV is not the workflow here, and per-user NFS authentication is not the key control being tested. The precise and supported action is to allow the ESXi host through the Filesystem Whitelist.
