The correct answer is associated with the type of resource record that is specifically designed for reverse name lookups within the Domain Name System (DNS). A PTR (Pointer) record is used for this purpose. When a DNS server receives a request for a reverse lookup, it essentially tries to determine the domain name that corresponds to a given IP address. The PTR record allows the server to map the IP address back to its associated hostname.

In contrast, other record types serve different purposes:

- An A (Address) record maps a hostname to its corresponding IPv4 address but does not help in reverse lookups.

- A CNAME (Canonical Name) record is used to alias one domain name to another, which is useful for domain redirection but unrelated to reverse lookups.

- An SOA (Start of Authority) record includes administrative information about a domain, such as the primary DNS server for the domain, but again, does not assist with reverse lookups.

Thus, the PTR record is the essential resource record for enabling reverse name resolution in DNS, making it the correct choice.
