The correct option is A) The speaker in the poem, as well as the chorus in the play, lament noble Antigone's terrible fate. In this poem, "Yeats" is adapted the Eros chorus from the Antigone. He not only explained love and how powerful it could be but also explained the power of fate and destiny, which is a topic of discussion in the original Antigone by Sophocles.
the chorus in the first half of Antigone play the role of commenting on the action and providing background information. This is often the role of the chorus in plays and musicals.
