c. nbtstat -a 193.145.85.202
Explanation:
Nbtstat is a TCP/IP utility which is used to display the current connections and statistics of TCP/IP using NetBIOS over TCP/IP (NetBT).
It is installed on a computer running Microsoft Windows when the TCP/IP protocol stack is installed.
Also, it is very useful when we want to troubleshoot NetBIOS name resolution problems.
One can run nbtstat -a < ComputerName > to obtain the local NetBIOS name table on <ComputerName> and its MAC address
