The correct option is B The Duma wanted Russia to participate in the First World War.
As a result of worker strikes, a legislative assembly called the Duma was formed by the Tsar. Ignoring the protest from the Duma, the then Tsar Nicholas II participated in the First World War, which broke out in 1914. Food shortage became severe by 1917. Thousands of women, along with workers and soldiers, marched in protests along the streets of Petrograd on 8 March 1917. The workers captured Petrograd, and Nicholas II was thrown out of power.
