D.

It increased deposition downstream.

Gunner · Answer 2

D. It increased deposition downstream.

Explanation:

Tailing is the material leftover after separation of valuable material from ore. Tailing ponds are made near moving water are not good for water as they increase water pollution. In case of waste rocks from mine dumped near water body such as river, may reduce the depth of river bed and increase chances of flood. These deposits also increase deposition downstream and form big deltas.
