What mistake did robespierre make as a leader of the revolution? what was the result?

No relationship in the French Revolution offers more eloquent testimony to the power of those human and personal forces which shape or alter history than does the struggle between George Jacques Danton and Maximilien Francois Marie Isidore de Robespierre. The difference between the two men was almost entirely one of temperament and opinion. Ideologically and politically, their views had some similarities. Both men hoped to have the Republic of their dreams based on a system of law and civic order.

The answer is c. good luck : )
