Final answer:
The Temple of Minerva is located in the ancient Etruscan city of Veii, as confirmed by the archaeological evidence of the Portonaccio temple's remains. Option C is the correct answer.
Step-by-step explanation:
The ancient Etruscan city where the Temple of Minerva is located is Veii. Archaeological evidence, such as the remains of the tufa-block foundations of the Portonaccio temple, has helped scholars understand more about these temples and the deities they were dedicated to. The temple's foundations suggest it faithfully followed the proportions described by Vitruvius, with a nearly square footprint. Furthermore, Etruscan temples typically had low wooden roofs covered in tile, extended beyond the foundation to protect the mud brick structure, and featured akroteria on the roofline for increased visibility of their sculpture.
Unlike Rome, Athens, or Nimes, the city of Veii is the definitive location where detailed archaeological studies have uncovered substantial evidence of the Temple of Minerva.
