An NFS server exports a directory to a client with the option `no_root_squash`. The administrator is concerned about security. What is the primary risk of this configuration?

Root users on the client have root privileges on the server for the exported directory.

All users on the client are mapped to the anonymous user.

The export is read-only, preventing writes.

The client cannot mount the export.
