The data link layerB. The application layerC. The protocol layerD. The access layerE. The session layerF. The network layerG. None of the above

参考答案和解析
正确答案：E
解析：Explanation:
TCP/IP includes ICMP, a protocol designed to help manage and control the operation of a TCP/IP network. The ICMP protocol provides a wide variety of information about a network's health and operational status. Control message is the most descriptive part of a name. ICMP helps control and manage IP's work and therefore is considered part of TCP/IP's network layer.
