Answer:
C) Group polarization
Explanation:
According to studies conducted by various sociologists, it can be said that this scenario provides an example of Group Polarization. This term refers to when groups make decisions that are far more extreme than what the members actually decide individually. Which is the case in this scenario since seperately they believe that Ms. Akey may be a better teacher but are not totally convinced. While together they believe that Ms. Akey is a far better (extreme) teacher.
