Correct answer: A
Answer: HTTP, FTP
HTTP: Clients often open multiple TCP connections to the same server to download resources in parallel (older HTTP/1.0 behavior and modern browsers), and even with persistent connections there may be multiple concurrent connections for performance.
FTP: Uses a separate control connection plus one or more data connections (active/passive modes). FTP frequently opens additional TCP data connections for file transfers and listings, so multiple TCP connections between the same client and server are normal.
Because both protocols can and do use multiple TCP connections between the same client and server, the pair HTTP, FTP is the correct choice.
