What does the option "Add Constraint" in Solver allow you to do?

The option "Add Constraint" in Solver allows you to limit the values of cells involved in your optimization calculations. This feature is crucial as it enables you to set specific conditions that must be met for the solution to be considered feasible. For instance, if you are working on a financial model and need to ensure that certain values remain within designated limits (such as production quantities or budget amounts), adding a constraint will enforce these limits during the optimization process. This helps achieve realistic and practical solutions based on given requirements or restrictions, ensuring that the final outcomes comply with specified criteria.

The other options provided focus on different functionalities: expanding the cell range pertains to the selection of data for analysis rather than imposing limits, changing the method of optimization relates to altering how Solver approaches the problem, and resetting parameters clears previous settings but does not create new limitations.
