The constraint X₁₃ + X₂₃ F1F1F1S1F1F1F10 X₃₄ F1F1F1S1F1F1F10 50 represents a flow balance equation at node 3, which means that the inflow of units and outflow of units should be equal. Since the coefficient of F1F1F10 is positive (indicating outflow) and there are no other outflows from node 3, we can conclude that 50 units will be shipped from node 3. Therefore, choice B is incorrect as it implies that 50 units will be shipped in to node 1, which is not mentioned in the constraint. Choice C is also incorrect as it implies that node 1 is involved in the flow balance equation, which is not the case. Choice D is also incorrect as the constraint only specifies the flow balance equation at node 3, but does not mention anything about the flow passing through it.
