C. It caused the levees to break

Explanation:

The loess can be defined as the clastic and stilt sized sediments that get accumulated due to the erosion of the mountain rocks and soil near the banks of river via wind and water erosion. The material is loamy and yellowish brown in color. It causes the yellowing of the river. It will break the levees. The levees are the artificial walls or natural walls that break with the excess flow of water or extra deposition of sediments on them due to loess. The levees prevent the flow of water in undesirable direction. The levees prevent the flow of water in the habitation and also prevents the flood. The uncontrolled flow of river due to the breakage of levees can cause flood.
