Show answer & explanation
Correct answer: B
Answer: IMAP
Why this is correct:
IMAP keeps messages on the mail server and synchronizes message state (read/unread, folders, flags) across multiple devices, allowing the same mailbox to be accessed from any machine.
POP3 downloads messages to a local device and typically removes them from the server, so it does not provide a consistently synchronized central repository.
SMTP is used to send email between clients and servers or between mail servers; it is not used for storing or providing synchronized access to mailboxes.
DMSP is not a standard email storage/access protocol and is not used for maintaining a central mailbox.
In summary: IMAP is the protocol designed to maintain emails on a central server and provide synchronized access from multiple machines.
