Answer: The correct answer is Conflict Theorist.
Explanation: Conflict theory in sociology refers to the vision of society (proposed by Karl Marx) that sees society as the perfect playground for conflict to arise.
The conflict may arise because there are limited resources in said society, thus, groups of people will form to compete for those resources.
In that prone to conflict field, those who have more power, wealth and riches will do anything to maintain their wealth and social position and will be called oppressors.
In conclusion, the fact that Jack disagrees with his parents because he believes that the law is created by those who control society in order to mantain their wealth and social position makes him a Conflict Theorist.
