Correct answer: A
Correct answer: Root server → TLD server → authoritative server → returns IP address.
When the answer is not already cached, a resolver starts from the DNS root servers.
The root server refers the resolver to the appropriate TLD server, such as .com or .org.
The TLD server then points to the authoritative server for the domain, and the authoritative server provides the final record, such as the IP address.
