The correct answer is option D. "ping ipv6" is the command that can be used to verify the live and responding state of a 128-bit IPv6 address.

IPv6 addresses are 128 bits in length, which is much longer than the 32-bit IPv4 addresses. The ping command is a network diagnostic tool used to test the reachability of a host on an IP network. The ping command sends ICMP echo request packets to the specified destination host and waits for a response. If a response is received, it means that the host is live and responding.

To verify a 128-bit IPv6 address, the "ping ipv6" command can be used. This command sends ICMPv6 echo request packets to the destination IPv6 address and waits for a response. If a response is received, it means that the IPv6 address is live and responding.

Traceroute is a command used to trace the path that packets take to reach a destination. It is not used to verify the live and responding state of an IPv6 address.

Telnet is a network protocol used to establish a connection with a remote host. It is not used to verify the live and responding state of an IPv6 address.

In summary, to verify the live and responding state of a 128-bit IPv6 address, the "ping ipv6" command is used.
