Answer: B

Explanation:

The port used for full synchronization between cluster members is TCP port 2654. This port is used by the Firewall Kernel to send and receive synchronization data, such as connection tables, NAT tables, and VPN keys4. UDP port 8116 is used by the Cluster Control Protocol (CCP) for internal communications between cluster members4.
