The correct answer is D. 6.
The Internet Protocol (IP) is responsible for addressing and routing packets across a network. However, IP does not provide any guarantees that the packets will be delivered in the correct order or that they will be received by the destination host. To overcome these limitations, higher-level protocols such as the Transmission Control Protocol (TCP) are used.
TCP is a connection-oriented protocol that provides reliable and ordered delivery of packets between applications running on different hosts. TCP breaks data into small chunks called segments and assigns sequence numbers to each segment. The receiver acknowledges receipt of each segment, allowing the sender to retransmit any lost or corrupted segments.
Each IP protocol is identified by a unique number assigned by the Internet Assigned Numbers Authority (IANA). The protocol number is included in the IP header to indicate which protocol is being used to process the packet. TCP is assigned the protocol number 6, while the User Datagram Protocol (UDP) is assigned the protocol number 17.
In summary, the correct answer to the question is D. 6 because TCP is assigned the protocol number 6.
