Final answer:
The Expressionist theory evaluates art based on the emotional impact it makes, expressing feelings, moods, and ideas.
Step-by-step explanation:
The aesthetic theory that judges art based on how well it expresses feelings, moods, and ideas is the Expressionist theory. This theory focuses on the emotional experience of the art, rather than its literal representation (Mimetic theory) or its formal elements and composition (Formalist theory). The theorists behind Expressionism argue that art should evoke feelings and convey the emotional state of the artist to the viewer, allowing for an emotional interaction with the work. So option d Expressionist theory is correct.
