a. cutting down trees
b. pouring motor oil down the drain
c. excess fertilizer use
d. none of the above

please select the best answer from the choices provided

a
b
c
d

Explanation:

• Cutting down trees removes root systems that hold soil in place. Without tree roots, rainwater can easily erode loose soil, washing sediment into water bodies and causing sediment pollution.
• Pouring motor oil down drains causes oil pollution, not sediment pollution.
• Excess fertilizer use leads to nutrient pollution (eutrophication), not sediment pollution.

Answer:

A. cutting down trees
