The answer is letter D. William Shakespeare's Sonnet 18 has a structure of fourteen <span>lines in an iambic pentameter with a </span>rhymed<span> couplet at the end. It has a rhyme scheme of abab cdcd efef gg. The first two lines rhyme with the third and fourth lines. The fifth and the sixth lines also rhyme with seventh and eighth lines, so as the ninth and tenth lines with the eleventh and twelfth lines. The thirteenth line rhymes with the fourteenth line, making them a rhymed couplet. </span>
dependant clause, cause we don't know who "who" is and the first sentance tells us this. If the sentence was on it's own without the context, we'd have no idea who "who" is.
I believe that the answer is
D) The king and queen place a high value on etiquette and manners
Hope this helped! :)
