Best answer
The correct answer is (a) Steel plants

Best explanation: Industries manufacturing aluminum, zinc and copper produce mud and tailings. So, that leaves the answer, i.e., steel plants. Tailings are the by-products left over from mining and extracting resources, such as extracting bitumen from oil sands or minerals such as copper or gold from ores.
