None of the given responses explain how appropriation helps artists express themselves. Appropriation is the act of borrowing, copying, or incorporating existing elements or ideas from other artists or sources into one's own work. By appropriating, artists can reinterpret, challenge, comment on, or make reference to the original work, which allows them to express their own ideas, perspectives, or criticisms. This process can enable artists to communicate, innovate, and contribute to ongoing artistic dialogues and conversations in unique and meaningful ways.
