Which among the following books is NOT written by Edward Said?

The correct option is Image-Music-Text.

To understand why this is the correct answer, let us look at the authorship of each of the books listed in the options:
1. On Late Style: Music and Literature against the Grain (published posthumously in 2006) is a work by the influential Palestinian-American academic and literary theorist Edward Said. It examines the work of artists and writers in their final years.
2. The World, the Text, and the Critic (published in 1983) is another major collection of essays written by Edward Said, exploring the role of literary criticism and the connection between literature and the world.
3. Image-Music-Text (published in 1977) is a celebrated collection of essays by the French literary theorist and philosopher Roland Barthes, translated and selected by Stephen Heath. It includes famous essays like "The Death of the Author" and "Introduction to the Structural Analysis of Narratives". It was not written by Edward Said.
4. The Question of Palestine (published in 1979) is a significant political and historical book written by Edward Said, presenting the historical relationship between the Arabs of Palestine and the Zionist movement.

Since Image-Music-Text was written by Roland Barthes and not Edward Said, it is the correct answer to the question.
