A rhyming couplet is two lines in a poem which rhyme and typically have the same meter, which means they have the same number of syllables. The correct answer is D. "<span>Her breath in mine, our fluent dipping knives-/ Never closer the whole rest of our lives"
A and B don't even rhyme, and C belongs to a quatrain, not a couplet, and those two lines don't have the same meter. D meets all the requirements of a rhyming couplet. </span>
