SMTP and IMAP are network protocols commonly used in sending and receiving emails. SMTP (Simple Mail Transfer Protocol) is used to send messages from a mail server to other mail servers. It's responsible for the delivery of the email to the recipient's server. IMAP (Internet Message Access Protocol) is used by email clients to retrieve emails from a mail server. Due to its support for synchronization of emails across multiple devices and the ability to view and manage emails on the server, IMAP is more commonly used in modern email systems. POP3 (Post Office Protocol version 3) is another protocol that can be used for receiving emails but it does not have the same features and functionality as IMAP. HTTP (Hypertext Transfer Protocol) is used for accessing web pages and is not typically used for sending or receiving emails. Therefore, the correct answer is A (IMAP) and B (SMTP).
