The correct answer is A) unlike Marxism, Marxism-Leninism includes a role for a small, elite group to help the people adapt to communism.
Marxism, founded by Karl Marx, emphasizes the idea of a class struggle leading to a classless society without a ruling elite. In contrast, Marxist-Leninism, as introduced by Vladimir Lenin, accepts the necessity of a vanguard party (an elite group) to guide the working class and implement the transition to communism, especially in the face of complex socio-political realities.
