B - "(...)Mobility data traffic is carried via Ethernet over IP (EoIP) which is IP protocol 97. This is the IP protocol number, not a TCP/UDP port value. Your firewall rules should allow IP protocol 97 traffic between your WLCs. For some background reading on EoIP, please see RFC3378 (...)" https://community.cisco.com/t5/wireless/eping-on-ip-port-97/td-p/1782329

Selected Answer: A
Answer A is correct. Tunnel is down. If the tunnel is down, data will not flow over it -> eping fails. Tunnel control messaging is sent over UDP 16666.

Given Answer is correct! The question asks which port should be allowed for COMMUNICATION to happen, not for eping to happen. CAPWAP uses UDP16666 for control plane.
