Why each option
DNS (Domain Name System) is the service responsible for resolving human-readable hostnames into numeric IP addresses.
Computer Browser is a Windows network service that maintains a list of computers and shared resources on a local network segment, not a name-to-IP resolver.
DHCP (Dynamic Host Configuration Protocol) dynamically assigns IP addresses and network configuration to clients, but does not perform hostname-to-IP resolution.
DNS operates as a hierarchical, distributed naming system defined in RFC 1034/1035 that maps fully qualified domain names (FQDNs) to IP addresses. When a client queries a hostname, DNS resolvers traverse the hierarchy from root servers down to authoritative name servers to return the correct IP address.
WINS (Windows Internet Name Service) resolves NetBIOS names - not standard hostnames or FQDNs - to IP addresses, and is a legacy Microsoft-specific technology.
