@Bikram sir

i have a doubt that  question is asking about largest network we choose option d  thts fine

but in general for all department,subnet of host,university  ,MAC address will be unique for specific host .

how spoofing will work?

---

If it would be talking about ip address than the answer should be department or university?

---

What would be the case if we are talking about IP address?

Answer 1

ans should be (A)

Answer must be D according to IPv6 protocol because in IPv6 MAC address itself the part of Ip address so..it's unique throughout INTERNET.
