   For me the correct is: IP protocol number 89

   6 –> TCP
   89 –> OSPF
   179 –> BGP

   Reference: http://www.iana.org/assignments/protocol-numbers/protocol-numbers.xhtml

   Anyone has other sugestion?

   option A is correct
   OSPF does not use a TCP/IP transport protocol (UDP, TCP), but is encapsulated directly in IP datagrams with protocol number 89
