The answer to the question: Why did most revolutions end by 1850, would be, A: People stopped supporting war and conflict.

Explanation:

By 1850, especially in Europe, most people were tired of the multiple wars between their countries, and the conflicts generated within by the differences especially in social status, and power and control. In fact, the most relevant factor that brought most revolutions to an end, and prevented new ones from springing, is that people stopped supporting their rulers, or leaders, and chose to support instead a life of peace, and quiet. Also, this lack of support brought rebellious people to a stop, since they too could not find the necessary support in their fellow citizens. This is why the answer is A.
