Answer:
HI! I would say that the best option is B mentoring.
Step-by-step explanation:
Well, productivity refers to how much one person is producing, how much work they are doing. But, does not refer to them motivating others. Modeling, is a process that allows you to analayze the buissness process, again not motivating anyone. And lastly, perpetuity. has do with money. So, mentoring which is helping others/ motivating them, would be the best answer.
Hope this helps you!
