The correct answer is C.) artistic values of ancient Greece and Rome.
Neoclassicism means 'New classicism,' so it is obvious that this particular era drew its influences from the Classical era of ancient Greece and Rome. Artists within the era of Neoclassicism thought that the greatest artists came from ancient Rome and Greece and therefore wanted to try and imitate their art. This especially reflected in paintings and literature, with artists such as Angelica Kauffman, Domenico Vantini (painters), T. S. Eliot, Alexander Pope (writers).
