The correct answer is C. Arches.
Explanation
The arch is the name by which a type of semicircular structure is known, which is used as a support for buildings because it provides great stability to them, due to the distribution of the load that allows it to support large amounts of weight. This form of architecture developed in ancient civilizations like Mesopotamia. However, its greatest use was in ancient Rome, where it was used in different structures with domestic functions such as sewers, aqueducts and bridges; and larger buildings such as theaters and the monumental Roman Coliseum. So, the correct answer is C. Arches.
