Which significant literary figure is associated with the British Victorian period?

Charles Dickens is a prominent literary figure associated with the British Victorian period, which spanned from 1837 to 1901 during the reign of Queen Victoria. Dickens's works, such as "A Tale of Two Cities," "Great Expectations," and "Oliver Twist," are foundational texts of this era and offer keen insights into Victorian society, including its social issues, economic changes, and the human experience. His storytelling is characterized by rich characters and intricate plots that often highlight the struggles of the poor and the inequalities of the time.

In contrast, Edith Wharton was an American author who is best known for her works that explored the American upper class during the late 19th and early 20th centuries, while Walt Whitman and Ralph Waldo Emerson were key figures in American literature, promoting transcendentalism and poetry, particularly in the 19th century. Although their contributions to literature are significant, they are not tied to the Victorian period in Britain in the same way that Dickens's works are. This distinguishes Dickens as a quintessential representative of that literary era, making him the correct answer.
