Why each option
SMTP (Simple Mail Transfer Protocol) is the standard protocol used to send and relay outgoing email messages between servers and from clients to servers.
RDP (Remote Desktop Protocol) is used to remotely access and control another computer's desktop, not for email transmission.
NTP (Network Time Protocol) synchronizes time across network devices and has no role in email transmission.
POP3 (Post Office Protocol version 3) is used to retrieve and download incoming email from a server to a client, not to send outgoing email.
SMTP operates on port 25 (or 587 for submission) and is specifically designed for transmitting outgoing email. It handles the transfer of messages from a mail client to a mail server and between mail servers during relay.
