Final answer:
The term for buildings that don't require specialized skills and are constructed in a style native to a particular region with local materials is called Vernacular architecture. (option A)
Step-by-step explanation:
The common language of building that doesn't require specialized skills is referred to as Vernacular architecture. This type of building is based on local needs, and available materials, and reflects local traditions. It is typically built by amateurs without the use of plans by professional architects and may not conform to any particular style, unlike Baroque, Gothic, or Classical, which are more specific architectural styles with defined characteristics that often require skilled craftsmen to construct.
Vernacular architecture is in contrast to architectural styles like Baroque, Gothic, or Classical (options B, C, and D), which are more formal and often require specialized skills and knowledge for their construction. Baroque architecture is known for its ornate and elaborate style, while Gothic architecture is characterized by pointed arches and ribbed vaults. Classical architecture, on the other hand, follows the principles of ancient Greek and Roman design, emphasizing symmetry and proportion.
