Final answer:
Brainstorming is not a part of the solution selection process in a group setting; it is used earlier for generating ideas. Selecting a solution involves evaluating and deciding amongst available options.
Step-by-step explanation:
When a group is selecting the best solution to a problem, brainstorming is not typically part of the selection process. Instead, brainstorming is used earlier in the problem-solving process to generate ideas and possible solutions. The options that involve decision-making in the selection phase include voting, ranking, rating, building consensus, and compromise. These methods are aimed at evaluating the existing ideas rather than generating new ones. Therefore, the correct answer to the question, 'Which of the following is not something your group might do while selecting the best solution?' is 'b. brainstorm'.
