Answer :
The correct answer is d. Prior to configuring the Solver variables, you need to ensure that you create a spreadsheet model that can be used to manipulate the values for your constraints.
Excel's Solver is a powerful tool for optimization, requiring careful consideration of results. Users should be skeptical and understand its convergence criteria for accurate outcomes. You do not need to create a spreadsheet model specifically to manipulate values for constraints before configuring Solver, even though having a model is generally useful.
