Works well in unidirectional communication, suitable for broadcast information.
B
It does three way handshake before sending datagrams
C
It provides datagrams, suitable for modeling other protocols such as in IP tunneling or Remote Procedure Call and the Network File System
D
The lack of retransmission delays makes it suitable for real-time applications
Explanation:
