Final answer:
To find the path between two computers, you should use the traceroute utility. It shows the route packets take to reach the destination and helps to pinpoint delays in the network.
Step-by-step explanation:
The utility you would use to find the path between two computers is B) traceroute. This network diagnostic tool traces the path that a packet takes from the source to the destination computer. It enables you to identify where any delays or blockages occur in the path, providing each hop and the time taken to get to each hop. Unlike traceroute, nslookup is used for querying the Domain Name System to obtain domain name or IP address mapping, ping is used to check the reachability of a host on an IP network and measures the round-trip time for messages, and ipconfig is used on Windows-based systems to display all current TCP/IP network configuration values and refreshes Dynamic Host Configuration Protocol (DHCP) and Domain Name System (DNS) settings.
