Which of the following novelists did not employ “Stream of
Consciousness” technique?

The correct option is Graham Greene.

To understand why this is the correct answer, let us look at the literary styles of each of the writers listed:
1. Virginia Woolf: She is one of the most famous pioneers of the modernist "Stream of Consciousness" technique, using it extensively in novels like Mrs. Dalloway and To the Lighthouse to depict the inner thoughts and feelings of her characters.
2. James Joyce: His masterpiece Ulysses is celebrated as one of the definitive examples of the stream of consciousness technique, capturing the raw, unstructured flow of thoughts in the human mind.
3. Dorothy Richardson: She was one of the earliest writers to use this style, particularly in her multi-volume novel sequence Pilgrimage. In fact, the term "stream of consciousness" was first applied to English literature in a review of her work.
4. Graham Greene: Unlike the others, Greene wrote in a more traditional, realistic narrative style. His novels, such as The Power and the Glory and The Quiet American, focus on moral, religious, and political themes using structured, linear storytelling rather than the stream of consciousness technique.
