D. ping 127.0.0.1
E. tracert 203.125.12.1
F. None of the above
D 解析：Explanation:
Every Windows based PC uses the 127.0.0.1 as the local loopback IP address. Every PC will respond to this local IP address if the TCP/IP stack is correctly installed and running on the machine. If you cannot ping the loopback address of 127.0.0.1, then something is wrong with the TCP/IP protocol stack
