The correct answer is: "It does not represent any objects or subjects from the real world."
Autumn Rhythm (Number 30) is an example of nonrepresentational or abstract art because it does not depict any recognizable objects or subjects from the real world. Instead, it is composed of purely abstract elements such as lines, colors, and textures. The painting is characterized by its rhythmic and gestural composition, with drips, splatters, and pours of paint applied with a variety of tools such as brushes, sticks, and trowels. Pollock's intention was to create a work of art that was not based on any preconceived ideas or forms, but rather to allow the painting to emerge spontaneously through the process of making it.
