Correct answer: B
IMAP (Internet Message Access Protocol) is a server-centric email retrieval protocol. Unlike POP3, which downloads messages to a single client and typically removes them from the server, IMAP keeps the messages on the mail server and lets the client manage them remotely.
Because the mailbox lives on the server, IMAP supports rich server-side management: the client can create, rename and delete folders, and it can set message flags such as \Seen (read status), \Answered, \Flagged and \Deleted. These flags are stored on the server, so the same state is synchronised across every device that connects to the account.
Evaluating the options: IMAP needs a valid login (user authentication is mandatory), it works over a TCP/IP connection across the Internet rather than only on local networks, and it is an online, server-based protocol, not an offline-only one. Auto-deleting mail from the server after download describes the default POP3 behaviour, not IMAP.
Hence the feature that correctly describes IMAP is that users can manage server-side mailbox properties such as read status and folders.
