Answer
Brief Explanations:
- The Berlin Conference (1885) was about colonizing Africa, not related to Germany declaring war on Allies.
- When Russia mobilized forces on Germany’s eastern borders, Germany saw it as a threat and declared war, which led to conflict with Allies.
- Great Britain declaring war on Germany is a response, not the cause of Germany’s declaration.
- The Austrian archduke’s assassination was the spark for WWI but not the immediate cause of Germany declaring war on Allies.
Answer:
B. Russia mobilizes its forces on Germany’s eastern borders.
