An open-pit iron mine has been abandoned for several years. Before they left, the miners filled in the pits with soil that included tailings and other iron containing waste products from the mine's productive years. Which of the following hazards do the pits most likely pose to the surrounding environment? I. Acid mine drainage
II. Cyanide leaching
III. Increased carbon emissions

A.) I only
B.) II only
C.) III only
D.) I and III only

I. Increased carbon emissions

seems to be unlikely/wrong, so options c and d are out

I would go with a, but it's almost 50/50 to b.

my best advice is that c and d are nonsense based on III and I
