Final answer:
The right of teachers to make assignments is an example of legitimate power, which is based on their formal role within the educational system.
Step-by-step explanation:
Teachers have the right to make assignments by virtue of their position as educators within a school. This right exemplifies legitimate power, which is power vested in a person's role or position within a legal or formal structure. In the context of a classroom, when students accept their teacher's authority to give assignments and grade them, they acknowledge the teacher's legitimate power. This concept aligns with sociologist Max Weber's definition of rational-legal authority, which is based on rules, regulations, and laws—in this case, the educational system's policies and the school's administrative rules.
