Answer: (ii) connection less

UDP (User Datagram Protocol) is connectionless: it sends independent datagrams with no handshake, no connection state, no acknowledgements, and no retransmission. It is unreliable but fast and has low overhead, so it suits DNS, streaming, VoIP, and gaming. TCP is the connection-oriented transport protocol.
