What is the difference in data transmission delivery and reliability between TCP and UDP?

The correct answer is D. TCP requires the connection to be established before transmitting data. UDP transmits data at a. UDP speeds up transmissions by enabling the transfer of data before an agreement is provided by the receiving party. As a result, UDP is beneficial in time- sensitive communications, including voice over IP (VoIP), domain name system (DNS) lookup, and video or audio playback.
