The correct answer is D. The rhyme pattern in William Blake's "The Tyger" is considered regular because the rhyme scheme is repeated throughout the poem in each stanza. The rhymes in each stanza are as follows: bright and night, skies and eyes, aspire and fire, art and heart, beat and feet, chain and brain, grasp and clasp, spears and tears, see and thee, and then again bright and night as the first stanza is essentially repeated.
