The correct answer is D) the Inca were organized to achieve complex projects.
The cultural information that the architecture of Machu Picchu provides is that the Inca were organized to achieve complex projects.
The Inca were a smart civilization in what today is Peru, in South America. They had pre-Columbian architectonic projects that astound modern architects for the complexity they had and the irregular land over where they built their cities like Machu Picchu, at the top of a mountain. They built complex stone structures with a uniform design for homes and public buildings. Historians consider that the Incas were organized to achieve complex projects not only in architecture but in farming. They had good farming techniques despite growing crops at the tip of the mountains and slopes.
