Consider the flow from S to T in the network below. Flow and capacity (F:C) are defined for each link. 

Which alternative represents possible values of flow/capacity for the variables x, y, w, z:

1. x=3, y=4, w=2, z=5
2. x=2, y=4, w=2, z=6
3. x=3, y=5, w=2, z=4
4. x=3, y=5, w=1, z=5
5. None of the above
