    1. the correct answer is A, because the SLAAC uses network prefix + EUI64
      so Network Prefix:2345:: + EUI64 = MAC Address converted to EUI64
      How that is work:

      MAC Address: 0300.1111.2222
      Divided into 2 pieces + Insertion of (FFFE)= 0300.11 FFFE 11.2222
      Then the second rule is to flip 7th bit of 1st byte (0 to 1 or 1 to 0), you have to convert the first 2 numbers into binary in order to solve this= (03) binary 0000 0011 flip the 7th = 0000 0001, so the result it would be= 01 instead of 03
      so result = 2345::100:11FF:FE11:2222

      You can search on EUI64 conversion on youtube.
