In problem formulation, the objective is expressed in terms of the decision variables, along with the constraints. The decision variables are the unknowns that need to be solved for, and the objective function is the measure of the success or failure of the solution. Therefore, Option A is correct. Option B is incorrect because the constraints are themselves expressed as equations or inequalities in terms of the decision variables. Option C is incorrect because nonnegativity constraints are one of the most common types of constraints and are not always ignored. Option D is incorrect because the optimal solution is the solution that satisfies all constraints and minimizes or maximizes the objective function, but it is not decided upon initially during problem formulation.
