Hello :)
Maximilien Robespierre was the leader of the revolutionary government who led the Reign of Terror a radical, uncompromising, and rather ruthless (born 1758 – died 1794) . Georges Danton was the first committee leader, but was later replaced by Maximilien Robespierre. Anna Maria Tussaud was a french artist famous for wax sculptures, so she definitely is not the extreme radical leader. Louis XVI was the last king of the french revolution before the monarch fell. So the best answer here would be A. Maximilien Robespierre
