Answer:
A). Because people have different ideas about the subject that could lead to conflict and anger.
Step-by-step explanation:
Racial issues are by nature controversial due to several reasons. As per the question, the reason for discussions relating to the race being controversial is that people have different ideas and perceptions regarding the specific subject matter that leads to conflict that evokes anguish and anger. Every individual carries certain personal ideas, beliefs, and perceptions based on their background and due to this people often feel offended when they are being contradicted by another individual coming with a different perception. This arises conflict and develops feelings of anger as a consequence of the clash of two or more critical thoughts together. Thus, option A is the answer. To conclude, despite the conflicts, these discussions are quite comprehensive and we should promote these kinds of discussions.
