The correct answer is C. AAAA.
AAAA (pronounced as "quad A") is a DNS record type used to map an IPv6 address to a domain name. This allows clients to resolve the domain name to an IPv6 address, which is necessary for communication over an IPv6 network. The AAAA record type was introduced as part of the transition from IPv4 to IPv6 and is commonly used in modern networking environments.
The other DNS record types mentioned in the question are:
A - maps a domain name to an IPv4 address. PTR - maps an IP address to a domain name (reverse DNS lookup). SRV - specifies the location of a service or resource on the network.
While A and PTR records are commonly used in DNS, they are not relevant to resolving IPv6 addresses to domain names. SRV records are also not used for this purpose.
Therefore, the correct answer is C. AAAA.
