How do TCP and UDP fit into a query-responsible model?

  • A TCP avoids using sequencing and UDP avoids using acknowledgments
  • B TCP establishes a connection prior to sending data, and UDP sends immediately
  • C TCP encourages out-of-order packet delivery, and UDP prevents re-ordering
  • D TCP uses error detection for packets, and UDP uses error recovery.
Explanation

TCP is a connection-oriented transport protocol, so it establishes a connection before transferring application data. UDP is connectionless, so it transmits datagrams without a prior connection setup. That is the core behavioral difference described by the correct option.
