I agree.

Lenin believed that the socialist revolution could succeed in Russia if a small group of dedicated revolutionaries controlled the government. Here's the explanation:

1) Becoming an industrial state: Lenin believed that the industrial development of a country was a crucial precondition for a successful socialist revolution. Industrialization would create a large working class, which he saw as the potential driving force behind the revolution.

2) Peasants owning the land they worked: Lenin recognized that the majority of the Russian population were peasants who worked the land. He believed that by empowering the peasants and allowing them to own the land they worked on, they would have a greater stake in the success of the revolution and thus be more likely to support it.

3) Dedicated revolutionaries controlling the government: Lenin placed great emphasis on the role of a small group of revolutionaries in leading the revolution. He believed that a highly organized and disciplined vanguard party, comprised of committed and dedicated revolutionaries, would be able to seize political power and implement socialist policies effectively.

While all of these factors played a part in Lenin's thinking, your choice of the third point is correct. Lenin believed that a small group of dedicated revolutionaries, in control of the government, could guide and lead the working-class movement to establish a socialist society in Russia.
