Answer:
C) Not demanding a quick decision.
Step-by-step explanation:
C)
Each member of an effective team is encouraged to think individually, and then share his/her ideas in open discussion. After the ideas have been shared, each member will get a chance to reassess and fine-tune one's strategy after listening other member's strategies, and then discuss again. This whole process may take more time, so making quick decisions is avoided. Moreover if members are told that they have to make a quick decision, they will easily agree with other member's suggestion to save time, which will automatically reduce diversity.
Option A in incorrect because teams must have to consider and the discuss implementation of strategies.
Option B is altogether incorrect.
Option D is incorrect because such teams will clearly lack diversity.
