Which one of the following political theories advocates the withering away of the state and ushering in a new society in which there will be no state and no ceasses?

Marxism specifically advocates for the 'withering away of the state' after the proletarian revolution, envisioning a classless, stateless communist society. In Marxist theory, the state is seen as an instrument of class domination that becomes unnecessary when classes are abolished. Liberalism supports a limited state, democratic socialism retains democratic governance, and Fabian socialism advocates gradual reform without calling for state abolition.
