Read the line from "Sonnet 18" by William Shakespeare. But thy eternal summer shall not fade, What is the best paraphrase of this line?

Your youthful beauty will not disappear. (c)

In William Shakespeare's "Sonnet 18," the line best paraphrases to but your youth will never fade.

In "Sonnet 18" Shakespeare tries to compare a fair maiden to a summer's day, but he expresses that there is nothing that compares to her because her perpetual beauty and youth are far greater than such a temporary, inconsistent season.

So, when Shakespeare writes " But thy eternal summer shall not fade, " he is saying that her timeless youth will never fade, unlike the briefness of a summer's day.
