Name the poem that contains the line "Do not go gentle into that good night".

The line "Do not go gentle into that good night" is central to the poem of the same name written by Dylan Thomas. This villanelle, published in 1951, explores themes of resistance against death and the struggle for life. The poem is a passionate plea for fighting against the inevitable end, urging the reader to "rage against the dying of the light." It speaks to the human condition and the universal struggle with mortality.

While the other options include significant works by notable poets, they do not contain that specific line. John Donne's "A Valediction: Forbidding Mourning" deals with love and separation, while T.S. Eliot's "The Waste Land" and "The Love Song of J. Alfred Prufrock" address modernity and existential themes, respectively. However, none encapsulate the same confrontation with death as Thomas does in his poem. Therefore, the choice of "Do Not Go Gentle into That Good Night" by Dylan Thomas is unequivocally linked to the line in question.
