Which of the following describes a value conflict?

A value conflict occurs when individuals or groups have fundamental disagreements rooted in their core beliefs and values. In this case, the scenario describes a situation where one student's request for help with cheating directly challenges the fundamental value of academic integrity held by the other students. This represents a clash of ethical principles, highlighting the underlying values at stake.

The other options involve disagreements or differing preferences but do not center around fundamental beliefs. Disputes about working hours or project topics are more about logistical or personal preferences rather than conflicting values. Opposing views on school policies may reflect differing opinions or interpretations of those policies, but they do not necessarily engage with the core values that define an individual's moral or ethical beliefs. Thus, the scenario provided effectively illustrates a true value conflict.
