The most accurate response is:
Promotion of education made both rulers look less autocratic, and the Enlightenment was anti-autocracy.
Catherine the Great and Peter the Great promoted education as part of broader Enlightenment ideals, which emphasized reason, individualism, and the questioning of authority. By promoting education, they sought to create a more informed populace that could better understand and participate in governance, thereby presenting themselves as enlightened rulers rather than purely autocratic leaders.
