Explanation

set type=ns is the correct nslookup command because set is the actual interactive-mode directive that changes query parameters - typing set type=ns tells nslookup to request NS (Name Server) records for subsequent lookups. Options A, B, and D (locate, request, transfer) are not valid nslookup commands at all; they are fabricated terms that sound plausible but have no function in nslookup's interactive shell. transfer is particularly misleading because zone transfers are a real DNS concept (AXFR), but initiating one uses ls -d in nslookup, not a transfer type= command.

Memory tip: Think of set as the settings dial - in nslookup interactive mode, you always set something before you query, just like adjusting a setting before running a tool.
