The correct answer is D. They built irrigation channels to carry water where it was needed.

Cutting and stacking stones allowed early Andean civilizations to construct complex irrigation systems. By cutting stones into precise shapes and stacking them together, they created channels or canals to efficiently distribute water from rivers or other water sources to their fields. This enabled them to cultivate crops in areas that would otherwise be arid or receive limited rainfall. The ability to control and efficiently manage water resources was crucial for their agricultural productivity and the growth of their civilizations.

Option A, building walls to keep out invaders, is not directly related to the skill of cutting and stacking stones. While the construction of defensive walls may have been an important aspect of their civilizations, stone-cutting skills alone would not have contributed significantly to this purpose.

Option B, building large buildings to store food, does not directly involve the use of cut and stacked stones. While large buildings may have been constructed for various purposes, such as storage, the specific skill of stone-cutting is not uniquely linked to this activity.

Option C, building monuments to great leaders, also does not directly relate to the skill of cutting and stacking stones. Although stone-cutting techniques might have been employed to create impressive monuments, this particular purpose does not address how it helped Andean civilizations grow.

Therefore, the most accurate answer is D.
