A. B. C. D.A.
The BEST command that can help a network administrator query the NSs (name servers) for a remote application is the "dig" command.
The "dig" command stands for "domain information groper" and it is a commonly used tool for querying DNS (domain name system) servers to retrieve information about domain names, IP addresses, MX records, and other related DNS records.
With the "dig" command, a network administrator can query the name servers responsible for a particular domain name, retrieve information about the authoritative name servers for a domain, and perform various types of DNS lookups, such as A records, CNAME records, MX records, and more.
The "arp" command is used for querying and managing the ARP (address resolution protocol) cache on a local network, which maps IP addresses to MAC (media access control) addresses.
The "show interface" command is used to display information about network interfaces on a device, such as their status, configuration, and statistics.
The "hostname" command is used to display or set the hostname of a device on a network.
Therefore, the most appropriate command for a network administrator to query the NSs for a remote application is the "dig" command.
