Which of the following ports is used for HTTPS?

Port 25 is the default port used for SMTP (Simple Mail Transfer Protocol), which is for sending email.

Port 80 is the default port used for HTTP (Hypertext Transfer Protocol), which is the unsecured version of web communication.

Port 443 is the standard and well-known port for HTTPS (Hypertext Transfer Protocol Secure) traffic. HTTPS encrypts communication over HTTP using SSL/TLS, providing secure data transmission, and uses port 443 by default for these secure connections.
