I'm taking the same test and I think the answer that best fit this question is D because the question asks which line support the theme "true love last forever."
Looking at the options "it is an ever-fixed mark" and "tempest and is never shaken" seems like the best answer showing how true love last forever.
Let me know if I helped
Your answer is C..
if this answer is incorrect, then i am sorry..
An omission in a text is correctly punctuated using a dash. The answer is option B. In correcting, the long dash should be used. The punctuation dash in rather more formal, neat and presentable so the reader can still distinguish what it is omitted.
