Explanation

nslookup (Name Server Lookup) is the command-line tool specifically designed to query DNS servers and verify whether a hostname resolves to an IP address. A technician can run 'nslookup <website>' to confirm whether DNS resolution is working correctly for that site. Option B (hostname) only displays the local machine's hostname. Option C (tracert) traces the network path to a destination but does not specifically test DNS resolution. Option D (netstat) shows active network connections and listening ports, not DNS resolution.
