When William the Conqueror subdued England he gave them law at the point of the sword; and until we consent that the seat of government in America, be legally and authoritatively occupied

I looked this question up and found it refers to Sonnet 100 by William Shakespeare.

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.

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.
