a.UDP guarantees ordered delivery through sequencing
b.UDP performs a three-way handshake before sending data
c.UDP is connectionless and does not guarantee delivery
d.UDP always encrypts application data

UDP is connectionless, has low overhead, and does not guarantee delivery, ordering, or retransmission. This makes it ideal for latency-sensitive traffic such as VoIP and streaming. TCP, by contrast, is connection-oriented and reliable.
