Why each option
FTP (File Transfer Protocol) is a standard application-layer protocol defined specifically for transferring files between a client and a server over a TCP/IP network.
Holding and retrieving email messages is the role of POP3 and IMAP protocols; FTP has no involvement in mail storage or delivery.
Managing network devices is the function of SNMP (Simple Network Management Protocol), not FTP.
Serving files on the World Wide Web is the role of HTTP/HTTPS; FTP operates independently of the web and communicates with dedicated FTP servers, not web servers.
FTP, defined in RFC 959, is purpose-built to transfer files between computers over a network using a client-server model, operating on TCP port 21 for control and port 20 for data transfer.
FTP requires credentials (username and password) for authentication by default; while anonymous FTP allows public access, it still requires submitting a username and is not a general characteristic of the protocol.
