Answer: The right answer is the A) Classicist.
Explanation: Just to elaborate a little on the answer, it can be added that since the poem in the second instance will "likely be modeled after ancient Greek and Roman poetry," that implies that it will be a Classicist poem, since Classicism refers to a literary and an artistic style that conforms to the ideals and the principles of the Greco-Roman Antiquity—or the Classical Antiquity.
