B.
set protocols ospf3 router-id fe80:223:2887:ab31::1
C.
set routing-options router-id 224.1.0.1
D.
set protocols ospf3 router-id 10.8.3.9
D is correct. You set the router-id under routing options and A is not a valid 32 bit number in dotted quad notation.
Correction!! Correction!!B and D are incorrect. You set the router-id under routing options and A is not a valid 32 bit number in dotted quad notation.

NO! NO! The router id is a 32 bit number.C is the only valid answer!
A is IPv6 address, for validation visit http://www.intermapper.com/ipv6validator
“C” is the correct one, Router ID has to be 32 bit
C is the correct answer… it must be a 32 bit ID
C is the correct answer
“OSPFv3 Router IDs, Area IDs, and LSA link-state IDs remain at the OSPFv2 IPv4 size of 32 bits.”
