Why are the events from 1905 to 1917 called a long revolutionary process?

1905 opened unrest and 1917 ended Tsarism

The Russian Revolution was not an isolated event that suddenly began and ended in one year. The Revolution of 1905 exposed deep conflicts among the autocracy, workers, peasants and national groups. It produced strikes, peasant disturbances, military unrest and the first soviets, while forcing the Tsar to make limited constitutional concessions. These problems were not solved, and repression, social inequality, the land question and dissatisfaction with the monarchy continued. The First World War then intensified the crisis, leading to the February Revolution in 1917 and the fall of Tsarism, followed by the Bolshevik October Revolution. Option A is correct because it identifies 1905 as an opening stage and 1917 as the decisive culmination. The other options contradict the historical sequence or reduce revolutionary events to trade agreements.
