Answer:
c. sketch
Step-by-step explanation:
The drawing in question is a sketch and a study for Picasso’s famous piece, Les Demoiselles d'Avignon. We can deduct that he has changed many things in the finished painting, but that is the purpose of the sketch – to pose the basic idea.
Sketches are rapid drawings, often not intended to be finished or displayed. They can be done to just put the basic ideas and the concept of art, or to study the shapes, techniques, and practice the drawings. There are Picasso’s few other studies of the idea besides the presented one, as he has obviously tried different executions of the idea before doing the finished painting.
