The correct answer is. A. Status differences
Explanation:
In sociology and similar fields, the source of conflict refers to the reasons, circumstances or factors that lead to a conflict or clash between two forces, individuals, groups, etc. This source can be of different types depending on the nature of the conflict.
In the case presented, the main source of the conflict can be attributed to "status differences" considering Bethany who is one of the main parts involved in the conflict is a senior marketing manager, which means she has a higher status than Ken that is only supervising the group and because of this, Bethany probably believes she should not follow Ken and he should not be the leader but her. In this way, this difference between the status of Ken and Bethan makes Bethany resist Ken and take actions against him.
