A is correct. Private IPv4 addresses were developed to conserve IPv4 address space. NAT was developed as a way to use private addresses and allow for them to be able to communicate with other hosts outside of their LAN. C & D do not deal at all with private IP addresses

ipv6 doesnt need any preservation or conservation. It's got a metric fuck ton to the power of bazillion addresses. Whereas ipv4 is essentially already depleted.
