Which of the following is an example of Art Deco architecture?

The Ideal Theater by Pablo Antonio is a notable example of Art Deco architecture due to its distinctive stylistic elements that define the movement. Art Deco is characterized by bold geometric patterns, rich colors, and a sense of luxury and modernity, which is often reflected in the ornamental detailing and streamlined forms found in its buildings. Opened in 1930, the Ideal Theater showcases the multi-faceted design approach typical of Art Deco, including the use of vertical lines and stylized motifs that convey an air of elegance and progression, aligning with the broader cultural movements of the time.

In contrast, the other options represent different architectural styles. The Manila City Hall, for instance, is primarily influenced by the Neoclassical style, characterized by its formal balance and classical elements such as columns. The Manila Post Office, while also an important architectural work, is rooted in the Beaux-Arts style, which incorporates more elaborate ornamentation and grandiose forms inspired by classical architecture. SM Megamall, on the other hand, embodies more contemporary commercial architecture, focusing on functionality and modern commercial design rather than the decorative aspects that define the Art Deco style.
