Answer:
The principle of equality
Step-by-step explanation:
Although this question does not have the group of answer choices, this is the definition of the principle of equality.
In sociology, the principle of equality refers to the fact that all people should be treated as equals and that all the interests of all people are equally important regardless of characteristics such as gender, age, sexual orientation, social class. Therefore, it would be unjust to treat people differently unless we can show that there is actually a difference between them that is relevant to actually treat them in a different way.
