Why each option

The primary function of a DNS service is to translate human-readable domain names into numerical IP addresses, enabling network communication.

ATo dynamically assign network addresses to hosts

Dynamically assigning network addresses to hosts is the function of DHCP.

BTo translate domain names to IP addressesCorrect

The primary function of the Domain Name System (DNS) is to translate human-friendly domain names, such as 'www.example.com,' into their corresponding numerical IP addresses that computers use to identify each other on a network. This translation is essential for web browsing, email, and other internet services.

CTo authenticate users to remote servers

Authenticating users to remote servers is handled by authentication protocols like Kerberos or LDAP, not DNS.

DTo serve files over the network

Serving files over the network is the function of file servers, not DNS.
