After October declaring land as social property brought the biggest change in which social relation?

Correct answer: Landlord and peasant relation

The direct answer is option A: the relation between landlords and peasants. Land is the basis of livelihood for peasants and the basis of power and income for landlords. When land was declared social property after October, the old private control of large landowners was challenged. The reasoning is: landlords previously controlled land; peasants worked on or depended on that land; a new land policy weakened the landlord’s ownership and authority; therefore the landlord-peasant relationship changed most directly. Option A is correct because it identifies the social relation directly affected by land policy. Option B, church and trader relation, is not the main relation transformed by this land measure. Option C, foreign bank and army relation, concerns institutions unrelated to the immediate ownership and use of rural land. Option D, palace and teacher relation, has no direct connection with redistribution of land. The policy should be understood in relation to peasant demands for land and the abolition of old landlord privilege. “Social property” does not mean that every individual had identical personal use in every situation; it means the old landlord ownership and control were rejected in favour of a new social or state-directed arrangement. Memory cue: land policy directly changes the landlord-peasant relationship.
