D. a philosophical exposition on the value of art imitating life.
Explanation:
The passage shows how important art is. In the words of the author of the passage, art is not only important because it is beautiful or because it has the ability to make us reflect, but it is beautiful because it is a way of documenting important events in people's lives.
The passage provokes a philosophical exposition about the value of art that imitates life, asking us if all lives are being portrayed or just the life of a privileged group. This questioning is important because it reflects the value that art has in each person's life and if each person can identify with what is being exposed.
