Nike will build a factory at Millville or Greenfield, but not both.Alternatively, Nike may choose to build at neither location.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 correct linear constraint to express that Nike will build a factory at either Millville or Greenfield, but not both, or at neither location, is to ensure the sum of binary variables representing the decision to build at each location does not exceed 1. This allows for the possibilities of building at one location, neither, but not both simultaneously.
