The correct answer is C: Maine.
Explanation
Sir Henry Maine is one of the chief exponents of the Historical School of Jurisprudence, not the Sociological School. He is famous for his theory on the development of law in progressive societies, particularly the transition from "Status to Contract."
The other three jurists belong to the Sociological School:
Rudolf von Ihering (Option A): Often called the "Father of the Sociological School," he viewed law as a means to a social end and balanced individual interests against social interests.
Eugen Ehrlich (Option B): Famous for the concept of "Living Law," he believed that the actual law governing society is found in social life rather than in formal legal codes or statutes.
Roscoe Pound (Option Pound): The most prominent American sociological jurist, he introduced the concept of "Social Engineering," where law is used as a tool to balance competing interests in society.
