The answer is D (the person who answered above me is incorrect). The inca were organized to acheive complex projects.

From conquered populations, the Incas demanded a tax of labor. This tax could be paid with military service, construction work, or agriculture work. It was this organized and intensive system of labor that allowed the Incas to complete massive construction projects. The Incas built on the engineering accomplishments of the mother cultures that preceded them in the Andes region.

answer: this is because archeologists keep finding artefacts and ancient ruins dated more than 10000 to 15000 years, date around scientists said humans discovered language; which is at least mysterious as scientists always have said that is necessary to have a language to have architecture and some basic maths.
