The correct answer is B. Primary DNS Server.

DNS records are type of data that is equivalent to IP address where the website or domain is located.  DNS records are normally stored in DNS server in a raw or flat file. A host, using port number 53 will send a DNS request to the server. If the computer has stored it's data or record in it's database, it will automatically reply to the requesting host. Example: You typed in www.website.com, if you have a matching DNS record in your server, using an IP address, your server will reply and display the website.
