Which outcome arises when Inca agricultural terraces experience oversaturation?

A)Compaction-induced destabilization of terrace walls
B)Erosion reduction through enhanced root binding
C)Increased soil fertility via nutrient leaching
D)Improved drainage due to sediment deposition

💡 Explanation

Terrace oversaturation causes compaction, triggered by hydraulic loading, therefore destabilizing terrace walls. Because the mechanism is compaction, it damages long-term structural integrity, rather than improving drainage or fertility, which require porous and stable terracing.
