Why did the Provisional Government become weak by delaying the land question?

Correct answer: Because peasants' patience weakened and Bolshevik demands became more attractive

Land was a central issue for Russia’s largely peasant population. Many peasants wanted the estates of landlords to be redistributed, but the Provisional Government postponed a final decision and continued to focus on administration and the war. This delay disappointed rural people, encouraged them to seize land independently in some areas, and reduced their confidence in the government. The Bolsheviks gained political advantage by promising peace, land, and bread, so their programme appeared increasingly attractive to dissatisfied peasants and soldiers. Option A is correct. Options B, C, and D are false: the delay did not make landlords join the Bolsheviks, did not stop the war, and did not abolish the Duma.
