Why each option

NSLOOKUP is the standard command-line utility for querying DNS servers and retrieving DNS records such as A, MX, and NS records.

ANBTSTAT

NBTSTAT queries NetBIOS over TCP/IP statistics and name tables, not DNS records.

BNSLOOKUPCorrect

NSLOOKUP (Name Server Lookup) is designed specifically to query DNS servers interactively or in batch mode, allowing retrieval of detailed DNS information including IP address mappings, mail exchanger (MX) records, and name server (NS) records.

CPING

PING tests network reachability and round-trip latency to a host using ICMP echo requests; it does not query DNS record types like MX or NS.

DNETSTAT

NETSTAT displays active TCP connections, listening ports, and network statistics for the local machine; it does not query DNS servers.
