Answer:
The correct answer is D. Groupthink.
Step-by-step explanation:
Groupthink is a phenomenon that can be understood as the series of incorrect, dysfunctional and erroneus decisions and attitudes that a group of people make in order to preserve a feeling of harmony and conformity within the group.
In this particular case, Kirstie's boss asks for input about ways the company can improve its current advertising campaign but every time an employee suggests something that differs from the boss opinion the suggestion is ignored. In this case, it is likely that the group that is supposed to improve the company's advertising will experience the effects of Groupthink because they feel like in order to mantain harmony they'll just have to agree on whatever the boss is saying.
In conclusion, the correct answer is D. Groupthink.
