Final answer:
The correct choice for the type of conflict described, where disagreements become personal instead of remaining professional, is B) Interpersonal conflict.
Step-by-step explanation:
The type of conflict that refers to the emotional reactions when disagreements become personal instead of remaining professional is interpersonal conflict. Interpersonal conflict occurs when two individuals or groups of individuals clash and can happen for a variety of reasons, including differences in beliefs, values, opinions, and actions. When emotions run high in the workplace or any group setting, these conflicts can lead to stress, reduced morale, staff turnover, and decreased productivity. It's essential for conflicts to be addressed in a supportive environment where everyone involved feels heard.
Internal conflict, on the other hand, takes place within an individual and involves struggles of morals or emotions. A typical example of an internal conflict would be a character in a story who is torn between duty to family and duty to state. However, this is not the type of conflict described by the question.
