Final answer:
The correct answer is C) Serliana, which is a motif where an arch is surrounded by a pair of engaged columns with entablature, commonly found in Roman facades.
Step-by-step explanation:
Roman facades are often composed with the Serliana motif, in which an arch is surrounded by a pair of engaged columns with entablature. The Serliana, also known as a Venetian window, is characterized by a large central arch flanked by two smaller side openings with lintels, usually supported by columns or pilasters. This architectural feature was common in the classical architecture of ancient Rome and later during the Renaissance period. Engaged columns are columns that are partially embedded in a wall, which is a common trait in Roman architecture. They provide the depth and three-dimensionality to the structure's facade.
