The correct answer is D. All of the above
Explanation:
In art using and understanding space is one of the most important elements that allow artists to represent reality. This relevant aspect includes understanding how lights and shadows work to depict light and shadow in art; understanding same objects vary in size depending on their distance from a point; and also, understanding how one or more objects can overlap or be placed in from of others. These three aspects are important because they occur in real life and by mastering them the artist can represent reality in terms of distance and light/shadow. According to this, understanding and using space in art implies all of the above (varying size to create dept, darkening areas that should have a shadow, and placing part of one object in front of another).
