What did the survival of Bolshevik power in the Civil War indicate?

Correct answer: Reds gained control over opposing forces

The Russian Civil War tested whether the Bolsheviks could retain the power they had gained after the October Revolution. The Reds survived the conflict and defeated or contained the opposing forces, including the Whites and other enemies. Their survival showed that the new Bolshevik government had built enough military and political control to continue ruling over the core areas of Russia.

Option A is correct because it expresses the consolidation of Bolshevik authority over rival forces. The Tsar did not return peacefully, the Duma did not take all power, and foreign rule did not become permanent. Survival did not mean that every problem had disappeared; it meant that the Bolshevik regime remained in power after a major armed challenge and could begin strengthening its new political system.
