Which command must be applied to R2 for an OSPF neighborship to form?

Correct Answer:A

Note: The command network 20.1.1.2 0.0.255.255 area 0 can be used too so this answer is also correct but answer C is the best answer here.
The network 0.0.0.0 255.255.255.255 area 0 command on R1 will run OSPF on all active
