Why did Bolshevik policies weaken the power of noble landlords?

Correct answer: Their land and privileges were attacked

The direct answer is A: their land and privileges were attacked. Noble landlords gained power from large estates, hereditary titles and special social rights. Bolshevik policies changed this structure. Step by step: landlords’ property was seized or redistributed; aristocratic titles and old legal privileges were abolished; therefore their economic base and social authority became weaker. A is correct because it names both important sources of noble power. B is wrong because nobles were not given all banks. C is wrong because clothing or uniforms cannot itself transfer ownership and political authority. D is wrong because the Red Army did not make nobles kings; the revolutionary government opposed the old monarchy and aristocracy. The question tests a change in class power: land and privilege were removed from the old elite. Memory cue: remove land plus titles, and noble power falls.
