What is the PAN-OS NPTv6 feature based on RFC 6296 used for?
The NPTv6 feature in PAN-OS, based on RFC 6296, is used for IPv6-to-IPv6 network prefix translation. This technique involves translating the network prefix portion of an IPv6 address while maintaining the host portion unchanged, allowing for simple and stateless address translation at the boundary between two IPv6 networks.

Agree with B (IPv6-to-IPv6 network prefix translation) https://docs.paloaltonetworks.com/pan-os/9-1/pan-os-admin/networking/nptv6
B is correct https://docs.paloaltonetworks.com/pan-os/10-1/pan-os-networking-admin/nptv6/how-nptv6-works
When datagrams are going in the outbound direction, the internal source prefix is replaced with the external prefix; this is known as source translation
B is correct
