Option D, trying to increase the power of the monarchy, is the right answer.
Explanation:
Charles X was the King of France whose reign in France lasted between September 1824 to 1830. He wanted the monarchy to become more substantial than earlier in order to establish his full control over the nation. Therefore, the people of his nation did not like the changes he implemented in the system and launched the rebellion. Therefore, it may be said that the efforts made by Charles X to increase the power of monarchy sparked a revolution in France.
