      Dear bis,

      the key to answer this question is the IPv4 addressing of the computers. Both of them belong to the same IPv4 subnet 172.16.40.0/21, in other words they share the same link.
      Given that, you can test IPv6 communication using the Link Local IPv6 address.
      Answer C is the correct one.

          Given that A and B are malformed or invalid IPv6 addresses, it’s only a matter of RFC.
          Site-Local addresses (fec0::/10) are deprecated in RFC 3879.
          “Link-Local addresses are designed to be used for addressing on a single link for purposes such as automatic address configuration, neighbor discovery, or when no routers are present” (RFC 3513, section 2.5.6)
