Nike must build a factory at either Millville or Greenfield, but not both.The appropriate linear constraint to express this restriction using binary variables Y₁ and Y₂ is: A)Y₁ - Y₂$\le$ 1 B)Y₁ + Y₂ $\le$ 1 C)Y₁ + Y₂ = 1 D)Y₁ - Y₂$\le$ 0

The constraint should ensure that only one of the two locations can be selected, which is achieved by setting the sum of the binary variables to be equal to 1. Therefore, the appropriate linear constraint is Y₁ + Y₂ = 1.
