Which option identifies the step analogous to evaluating solutions in problem solving in the following scenario? ChemCo, a small specialty chemical company, sets a benchmark to recycle as much of their chemical waste stream as possible in one year. They gather data about the types and amounts of waste generated and identify what can be recycled. They also study how the large chemical manufacturing companies decide which waste is economically feasible to recycle. ChemCo chooses one of the identified strategies to try. After one year they evaluate the effectiveness of their strategy and realize their benchmarking process was flawed.
