Answer:
D. I may never live to write about them
Step-by-step explanation:
When I Have Fears is a Shakespearean sonnet (also called the Elizabethan or English sonnet) written by the English Romantic poet John Keats. The Shakespearean sonnet is a poem that consists of three quatrains (stanzas consisting of four lines) and a couplet (a stanza consisting of two lines).
John Keats wrote this poem in January 1818, but it was published only in 1848. The poem tells about Keats' fears as a poet, including that he may die before he has written the volumes and forms of poetry that he is convinced he is capable of writing. That's what the lines I may never live to trace / Their shadows, with the magic hand of chance refer to. Thus, the correct answer is D.
