Concept:This question tests knowledge of famous literary works and their authors from the English Romantic period.
Explanation:The poem "The Cloud" was written by Percy Bysshe Shelley, a prominent English Romantic poet. He published this poem in 1820. In the poem, Shelley personifies the cloud as a powerful, ever-changing force in nature. He explores themes such as beauty, transience, and the interconnectedness of all things. None of the other poets listed — William Wordsworth, Samuel Taylor Coleridge, or Lord Byron — wrote "The Cloud"; their famous works include "Daffodils," "The Rime of the Ancient Mariner," and "Don Juan," respectively. Therefore, only Shelley is the correct author.
