Correct answer & explanation

IPv6 host sends packet to synthesized IPv6 address

NAT64 allows IPv6-only hosts to reach IPv4 servers. The IPv6 host sends a packet to a synthesized IPv6 address representing the IPv4 destination. The NAT64 router receives the packet and extracts the embedded IPv4 destination address. It translates the packet header from IPv6 to IPv4, including source and destination addresses. The translated IPv4 packet is forwarded to the IPv4 network. When the reply comes back, the router performs reverse translation and sends the IPv6 packet to the host.
