Answer: D) groupthink
Step-by-step explanation:
Groupthink refers to a situation in which a group of people come together and make decision without thinking of the effect or outcome. People in the group collectively reach general agreement by giving optimum importance to the opinion and view of the group instead of individual’s opinion and view. It usually happens when groups have limited time to make decision and as a result they resolve to general opinion of the group. Thus, this is done in order to keep the unity and peace of the group.
