D Correct answer
Explanation

Web servers typically listen on port 80 for standard HTTP traffic. This is the well-known port assigned for HTTP by IANA. Ports 100 and 25 are used for other services (25 is SMTP for email), and 133 is not a standard web server port. Port 80 is the default port that web browsers use when no port is specified in a URL.
