Explanation
To answer this question, we need to identify the port numbers associated with email protocols used in client-server communication. Port 25 (SMTP - Simple Mail Transfer Protocol): This port is primarily used for sending emails between mail servers and from mail clients to mail servers (sending outbound mail). SMTP is an essential protocol for email traffic. Port 110 (POP3 - Post Office Protocol v3): POP3 is used for retrieving emails from a mail server. It is commonly used for downloading email messages to a local client, after which the messages are deleted from the server. While not as commonly used today (due to IMAP being preferred), POP3 is still a recognized email protocol, and its association with port 110 makes it a valid answer.
