Question

the most likely reason why napoleon could be classified as an enlightened monarch was because
he declared himself an enlightened monarch.
he implemented certain enlightenment ideals.
the pope blessed him as an enlightened monarch.
in comparison to his predecessor, he was enlightened.

Explanation:

Enlightened monarchs are defined by adopting and putting into practice key Enlightenment principles (like legal reform, secularization, and administrative rationality). Napoleon did this through actions such as the Napoleonic Code, which embodied Enlightenment ideas of equality before the law and religious tolerance, rather than self-declaration, papal blessing, or comparison to predecessors.

Answer:

he implemented certain enlightenment ideals.
