Which port is BGP?

Explanation:
BGP runs over TCP and uses a fixed port, which is 179. That combination—BGP over TCP on port 179—is why this is the correct choice. BGP is a routing protocol that exchanges reachability information between routers, and using TCP provides reliable, in-order delivery of its updates; the default port for this session is 179. The other ports map to different services: 443 is HTTPS, 143 is IMAP, and 1025 is not associated with BGP.
