Which one of the following is a wrong statement?

  • A.

    The dual of the dual is primal.

  • B.

    An equation in a constraint of a primal problem implies the associated variable in the dual problem to be unrestricted in sign.

  • C.

    If a primal variable is non-negative, the corresponding dual constraint is an equation.

  • D.

    The objective function coefficients in the primal problem become right-hand side of constraints of the dual .
