Correct answer: A
SMTP (Simple Mail Transfer Protocol) is an application layer protocol used to transmit email messages across the internet. It acts as a digital postal service that primarily pushes mail from a local client to a mail server, and then handles the multi-hop routing required to push that message from the sender's mail server over to the recipient's mail server.
