Answer:

Option B: DNS

Explanation:

Domain Name Server (DNS) is analogous to a phone book where people can look up a person name through numerical phone number. A DNS server is a database that host a database of public IP addresses (e.g. 64.233.160.0) and their associated hostname (e.g. google.com).
