C. ARIN Explanation: The scenario describes a reconnaissance phase technique called footprinting, which involves gathering information about a target organization in order to identify potential vulnerabilities or attack vectors. In this case, Clark has used Whois footprinting to obtain the server IP address of the target organization. He has then used an online tool to retrieve information such as the network range of the target organization and to identify the network topology and operating system used in the network. One such online tool that can be used for this purpose is ARIN (American Registry for Internet Numbers). ARIN is a non-profit organization that manages the allocation and registration of IP addresses and other Internet number resources in North America.
