Fig. $2.$ Where: Station A can communicate with D$.$

Station B can communicate with C$.$

Station C can communicate with B$.$

Station D can communicate with A$.$

Suppose that the stations use the protocol CSMA$/$CA with RTS $/$ CTS packets:

If station $B$ is transmitting to station $C,$ which of the following transmissions can start. Indicate if

it will be successful or not and if there will be a collision or not.
