Correct answer: authoritative, resolver.
Why this is the answer
Authoritative DNS servers hold the actual DNS records for a domain and provide definitive answers to queries. Resolver DNS servers (also known as caching DNS servers) receive queries from clients, then query other DNS servers (including authoritative servers) to find the requested information, and cache the results for future use. Web servers host websites, file transfer servers handle file uploads/downloads, and ESX hosts are virtualization platforms; none of these directly perform DNS name-to-IP resolution.
