What is the tone, mood, and the theme of Picasso’s painting La Guernica?

The overwhelming emotion comes from its large size are almost 11 feet tall and 22 feet wide. There are so many different animals and people in the painting. If you look on the back wall there is a sketch of something that looks like a human/animal sort of thing.

i think the answer could be either a or b because both are part of the post production part. hopefully this you a little.
