In order to be able to answer this, we'd need to know what book it is you're reading, as well as the answer choices as the question asks "which of the following best" meaning that they want you to choose the best answer from the choices they’re giving you.
This sentence would probably be a citation in APA style. Citations on research papers are very important since they give due credit to the original owner of the statement. Statements that don't have citations tells the readers that those statements are of the researcher/s alone which would be a problem for them if found out that it wasn't theirs to begin with. This would result to a work of plagiarism which is a grave sin in constructing research papers and is more equated with the act of stealing.
I looked this question up and found it refers to Sonnet 100 by William Shakespeare.
Answer:
The central idea of the sonnet is:
B. The speaker wants his muse to help him immortalize his love.
Explanation:
British writer William Shakespeare (1564-1616) is to this day one of the most famous names in literature. He wrote famous plays such as "Romeo and Juliet" and "Macbeth" as well as sonnets that are still appreciated and much studied.
<u>In Sonnet 100, the speaker addresses his muse. A muse is a goddess of the arts that can bring an artist inspiration. That is precisely what the speaker wants: inspiration to write about his beloved one in a way that will immortalize her. He is asking the muse to come back and start helping him find the words to do such a grand job.</u>
