• A. 443
• B. 80
• C. 21
• D. 8080

Answer: (B)

Port numbers in a URL are specified after the host, separated by a colon. They tell the client which network port to connect to on the server. In this URL, the portion after the host is :80, so the port number is 80. Port 80 is the standard port for HTTP traffic; HTTPS typically uses port 443, but the explicit :80 overrides the default and designates that port. The other numbers listed (443, 21, 8080) are common ports for other services or alternatives, but the value shown after the colon here is the port being used: 80.
