Correct answer: C
Correct answer: SMTP is used to send emails; POP3 is used to download them.
SMTP works as a mail sending/transfer protocol. It pushes outgoing messages from the sender’s client or mail server toward the recipient’s mail server.
POP3 is a mail access protocol. It lets a user download messages from a mail server to a local client, commonly for reading offline.
So the main contrast is sending/transfer by SMTP versus receiving/downloading by POP3.
