It looks to me like you are putting a question from a test or quiz down and hoping that one of us will just give you the answer. That is not what tutoring is.
However, just by looking at the answers to the question, even without knowing anything about sonnets, you can pretty quickly delete two of the answers, leaving only a 50/50 shot at the correct answer. Of those two remaining, one is definitely the obvious answer, especially if you've paid attention in your English classes.
A Shakespearean Sonnet also was written in Iambic Pentameter. Iambs are stressed/non-stressed repetitions and Pentameter is "5 meter". So 5 pairs of stressed and unstressed syllables for each line. The lines always followed a specific rhyming pattern. Specifically: ABAB CDCD EFEF GG
A Sonnet is quite difficult to write correctly. My roundabout answer can help you to find your answer if you take the time to learn something from it. But......I won't just give you the answer...you won't learn that way!
