Final answer:
Classical orders were first used in domestic architecture by Leon Battista Alberti in the 15th century, notably with the design of the Palazzo Rucellai, where he utilized elements of symmetry and proportion. Option A is correct.
Step-by-step explanation:
The classical orders are distinctive styles in classical architecture, each with its own proportions and decoration. The use of classical orders on a domestic building was first prominently exemplified by Leon Battista Alberti in Renaissance architecture, particularly with the design of the Palazzo Rucellai.
In the 15th century buildings such as the Palazzo Rucellai, Alberti applied elements of classical orders and architecture for aesthetic and symbolic purposes, including the use of pilasters and entablatures in a proportional relationship to each other, as a demonstration of symmetry and order.
Alberti's designs were heavily influenced by the Doric, Ionian, and Corinthian orders, which were developed in ancient Greek architecture and were characterized by their specific column and capital styles. The use of classical orders was done to show harmony, balance, and proportion in the building's design, making a statement about the knowledge and appreciation of ancient architectural principles.
These orders, including the Doric, Ionian, and Corinthian, exemplified knowledge and appreciation of ancient Greek architecture.
