The correct answer is: to the celluloid butterflies of her Beloved dead, / Lenin and Marx and Stalin arrayed at the footstead.
Explanation:
A rhyme represents the repetition of similar sounds in the final syllables of the last words in the verse.
In our case, the word dead rhymes with the word footstead. This is a single or masculine rhyme, as the stress is on the final syllable dead/footstead.
In other examples, there are no words which rhyme, so they cannot be considered as examples of the rhyme.
wing does not rhyme with erect
pillar does not rhyme with mirrors
window does not rhyme with brow
