Final answer:
Byron employs ottava rima in his work 'Don Juan,' characterized by an eight-line stanza and a specific ABABABCC rhyme pattern. The correct answer is option B.
Step-by-step explanation:
Byron uses ottava rima in Don Juan. This is a rhyming scheme that consists of an eight-line stanza with a specific rhyme pattern of ABABABCC, often in iambic pentameter. The excerpt given from Don Juan, with its characteristic double rhymes in the second and fourth lines and half rhyme/eye rhyme in the first and third lines, is indicative of ottava rima. This form is not used in "Tintern Abbey," which is a work by Wordsworth, nor in Byron's Childe Harold's Pilgrimage, which utilizes Spenserian stanzas. Therefore, the correct answer to the question is B. Don Juan.
