Final answer:
The work not authored by Virgil is A) Metamorphoses. Virgil's works include the Aeneid, Georgics, and Eclogues, whereas Metamorphoses was written by Ovid.
Step-by-step explanation:
The work that is not one of Virgil's works is A) Metamorphoses. Virgil is famous for his contribution to Roman epic poetry, with his works including the Aeneid, which represents the pinnacle of this genre.
The Aeneid tells the story of Aeneas, a Trojan who travelled to Italy, where he became the ancestor of the Romans. It's considered Virgil's most notable work and a cornerstone of Latin literature. Other works by Virgil include the Georgics, which are didactic poems about agriculture, and the Eclogues (also known as Bucolics), which are pastoral poemes.
Metamorphoses, on the other hand, was written by the Roman poet Ovid. It is a narrative poem which consists of a series of mythological tales involving transformations, and is considered Ovid's magnum opus.
