The statement that TCP is connection-oriented and verifies packet delivery is indeed accurate. TCP, or Transmission Control Protocol, is designed to ensure reliable communication between devices on a network. Being connection-oriented means that TCP establishes a connection between the sender and receiver before any data is transmitted. This process involves a three-way handshake, which helps ensure that both parties are ready for data transfer.

Once the connection is established, TCP tracks packets of data using sequence numbers and acknowledgments. If a packet is lost or not acknowledged by the receiving end, TCP will retransmit those packets, ensuring data delivery and order. This reliability aspect of TCP makes it suitable for applications that require accurate data transfer, such as web browsing or file transfers.

Other options present characteristics that do not apply to TCP. For example, TCP does not send packets in random order; rather, it ensures that packets arrive in the order they were sent. Additionally, it does guarantee data delivery, making option B inaccurate. Lastly, TCP functions within the framework of internet protocols, meaning it does not operate independently, which makes option D incorrect.
