Which DNS record identifies the primary name server for the zone?

Explanation:
The Start of Authority record is the one that identifies the primary name server for a zone. It contains the MNAME field, which designates the primary (master) DNS server responsible for the zone’s data. This distinguishes the main source of authority from other authoritative servers listed for the zone. PTR records map IPs to hostnames (reverse DNS) and aren’t about the zone’s primary server. NS records list the authoritative name servers for the zone, but they don’t specify which one is the primary. MX records designate mail servers and are unrelated to the zone’s name-server hierarchy.
