What is a feature of the Beaux-Arts architectural style?

The Beaux-Arts architectural style is characterized by its grandiosity and opulent detailing, which includes elaborate decorative elements. This style emerged from the École des Beaux-Arts in Paris during the late 19th and early 20th centuries and is heavily influenced by classical architecture, emphasizing symmetry, grandeur, and decorative richness. Architects who embraced the Beaux-Arts style often incorporated intricate sculptures, detailed facades, and monumental structures that reflect an ornate aesthetic, making it a symbol of prestige and cultural importance during its peak.

The other options do reflect different architectural movements or styles but do not align with the Beaux-Arts emphasis on opulence and ornamental detail. Simplistic lines are more associated with modern or minimalist designs; the use of steel and glass is characteristic of the modernist style that followed; and innovative geometrical shapes are often seen in contemporary or deconstructivist architecture rather than in the Beaux-Arts tradition.
