I believe the answer is: D. There are three economic classes: the rich, the poor, and the middle class.
The separation between these classes is based on their ownership of wealth&resources. The poor are those who barely have enough resources to keep living,
The middle class are those who can comfortably fulfil their basic needs while having a little bit of surplus that they can put into saving , while the Rich are those who had abundance of wealth & resources, to the point where they would not able to spend it in their lifetime.
Due to the fact that the paintings portray a view of heroism and victory in terms of the atmosphere and feeling that it gives off, one would assume that the outcome of these battles were a positive one, given the light in which they are painted and portrayed within.
the three nations of the Triple Alliance - Germany, Austria-Hungary, and Italy - stood against the three nations of the Triple Entente - France, Russia, and Great Britain
