Correct answer: C
Correct answer: UDP performs only transmission of segments (datagrams).
Explanation:
Segment/datagram transmission: UDP encapsulates application data into datagrams and sends them without establishing a connection.
No retransmission: UDP does not implement acknowledgements or automatic retransmission of lost packets; reliability must be handled by the application or by TCP.
No flow control: UDP does not regulate the sending rate based on receiver capacity.
No congestion control: UDP does not include congestion-avoidance algorithms; congestion control is a TCP feature (or implemented at other layers).
Summary: UDP is a lightweight, connectionless protocol that only transmits datagrams; it does not provide flow control, congestion control, or retransmission.
