In this network, which of the forwarding tables below ensures that both :

  • A and B can exchange packets in both directions
  • the path from A to B is the reverse of the path from B to A

In this network, A can send packets to B, but when B sends a packet to A, this packet never reaches its destination. Among the following forwarding tables, which is the one that ensures that A can exchange packets with B ?
