Answer:
Option B. The theme of "Ode to a Grecian Urn" is that beauty is eternal.
Explanation:
"Ode to a Grecian urn" is a poem written by the English poet John Keats in May 1818 and anonymously published on 1820 in an Art magazine. The central theme of the poem examines the eternity that beauty and truth holds and relates them to how our own lives are transcendent. For the speaker,it is through beauty that humankind connects to the truth, and how complex it is for us to comprehend that both concepts, truth and beauty, are indeed eternal while our existence is not. The speaker is not only meditating on beauty and its connection to art but at the same time is trying to understand the complex emotions that death awakens in him, and how inevitable it is.
