Which of the following works was also authored by W.H. Auden?

W.H. Auden is well-known for his poem "The Unknown Citizen," which explores themes of conformity, individuality, and the nature of modern society. This poem critiques the way society often evaluates a person's worth based on social status or public perception rather than personal achievements or inner qualities.

The selected work reflects Auden's distinctive style and thematic concerns, such as the dehumanizing aspects of modern life and the tension between individuality and societal expectations.

The other choices, while important works in their own right, are not authored by W.H. Auden. "The Armadillo" is by Elizabeth Bishop, "How Do I Love Thee?" is a sonnet by Elizabeth Barrett Browning, and "We Real Cool" is a poem by Gwendolyn Brooks. Each of these poets has a unique voice and style distinct from Auden's, thereby providing a clear distinction among the works listed.
