Correct answer: B
Answer: POP3 (Post Office Protocol 3).
POP3 is used by email clients to download messages from a mail server. By default, POP3 downloads messages and removes them from the server so they are stored locally on the client. However, many clients offer an option to leave copies on the server if you want to access the same messages from multiple devices.
Common ports: 110 for POP3, and 995 for POP3 over SSL/TLS (secure POP3).
How this differs from other terms you might know:
SMTP: used to send email between clients and servers or between mail servers (not for retrieving mail).
IMAP: keeps messages on the server and synchronizes state across devices; it does not typically delete messages after download.
MIME: a format for email content and attachments, not a protocol for sending or retrieving email.
