Answer:
C
Explanation:
Groupthink is defined as: "the practice of thinking or making decisions as a group in a way that discourages creativity or individual responsibility." In that situation, any decision reached has to be agreed by everyone, so the group's members are under pressure to make a decision. They will blindly accept any answer given to them.
A, B and D all discourage groupthink, since if the group is not together all the time, people will form different opinions of their own.
