Final answer:
After the attempted flight of the royal family, divisions among radical and moderate revolutionary groups in France became evident, leading to the execution of King Louis XVI and the onset of the Reign of Terror.
Step-by-step explanation:
After the attempted flight of the royal family, the outcome was C) divisions among more and less radical groups became apparent. As the constitutional monarchy failed to maintain power, radical political parties like the Girondins and the Jacobins grew in strength. The latter, supported by the sans-culottes, sought to abolish the monarchy entirely. When France declared war on Austria and the threat to the monarchy increased, these divisions became even more pronounced, with radical factions taking control. The Legislative Assembly suspended the king and created the National Convention, illustrating the chasm between various factions in the revolution. Disagreements between the Jacobins' moderate Girondins and the radical Mountain faction revealed the deepening rift among revolutionaries. Eventually, the radical Mountain prevailed, and King Louis XVI was executed in January 1793, cementing the division and setting the stage for the Reign of Terror.
