Option D is the correct answer because it is written in iambic pentameter.
An iambic pentameter refers to the line that has a pattern or rhythm that has to do with the number of syllables in the line and the emphasis placed on those syllables. In an iambic pentameter, from the word "pent", it's clear that the line has 5 stressed syllable.
For an iambic pentameter in a poem, every single line of that poem will definitely have five stressed syllables.
William Shakespeare's works are known to be often used as examples of iambic pentameter.
