The correct answer to the question of: which of the following is not a part of taking action, would be, C: Brainstorming.
Explanation:
Taking action is a process by which a person literally executes the ideas and plans that he/she forms to solve a problem or answer to a need. As part of this process, aside from executing a plan, the person needs to also establish the functions that different people will play in these plans, and also the person needs to follow through, or establish a follow-up plan to ensure that it is working, improve it, or make necessary changes. However, the only part that is not a portion of taking action is brainstorming, because this is the previous step to taking action. It is the pre-process of generating ideas to form a plan. That is why the answer is C.
