B
Correct answer
Explanation
Incoming email messages are handled by POP3 (Post Office Protocol version 3) and IMAP (Internet Message Access Protocol) servers. These protocols allow email clients to retrieve messages from the mail server - POP3 typically downloads and removes messages from the server, while IMAP keeps messages on the server and synchronizes across multiple devices. SMTP servers handle only outgoing email transmission, not incoming messages. Web and FTP servers serve different purposes, and SQL/AVG are database-related terms.
