Why each option
ICMP (Internet Control Message Protocol) is a network layer protocol used by network devices to send error messages and operational information, such as whether a requested service is unavailable or a host or router cannot be reached.
ICMP (Internet Control Message Protocol) is primarily used for diagnostic purposes and reporting errors concerning the processing of IP datagrams. It transmits control messages, including error messages (like "Destination Unreachable") and query messages (like "Echo Request" and "Echo Reply" used by ping for network statistics), between network devices.
DHCP (Dynamic Host Configuration Protocol) is used to assign IP addresses and other network configuration parameters to devices on a network.
TCP (Transmission Control Protocol) provides reliable, ordered, and error-checked delivery of a stream of octets between applications running on hosts.
NNTP (Network News Transfer Protocol) is used for reading and posting Usenet articles.
