Why each option
A typical DNS zone file is composed of various Resource Records that define how the domain's resources are organized and resolved.
DNS is the system itself, not a record type, and AXFR is a type of zone transfer, not a resource record.
DNS is the system itself, not a record type; while PTR records are crucial for reverse DNS, A, NS, SOA, and MX are fundamental to a forward zone file.
AXFR is a type of zone transfer, not a resource record found within a zone file.
SOA (Start of Authority) records are mandatory and define the authoritative server and zone parameters; NS (Name Server) records list the authoritative DNS servers for the zone; A (Address) records map hostnames to IPv4 addresses; and MX (Mail Exchanger) records specify mail servers for the domain.
