Answer: <u>Option C
</u>
<u>Explanation</u>: Hills are the most common source of sediments because they lack vegetation. Plants and trees hold the soil and thus prevent erosion of soil layer with water. The sediments from the hilly areas get carried by rain water or runoff, and add to the water bodies, like lakes and streams.
Waste from mining industries don’t have sediments in their waste, so option B is incorrect.
Option A is incorrect because over-irrigation will not affect the soil layer, as it is firmly held by the roots of the crops.
