C.
/pci@780/pci@0/pci@9/scsi@0then/pci780/pci@0/pci@1/networking@0

D.
/pci@780/pci@0/pci@9/scsi@0/disk@1then/pci780/pci@0/pci@1/networking@0,1

E.
/pci@780/pci@0/pci@9/scsi@0/disk@0then/pci780/pci@0/pci@1/networking@0

Explanation:
Note:
* second line in exhibit (minor typo):
boot-device = disk net
