d is correct

Explanation:

In metallurgy, the leaching is a method in which it can be separated two or more metals from the main ore. The use of bacteria contribute to this process because some microorganism can oxidize secondary products, leaving just the mineral that is important in the process.

Also the bacteria can digest some products that can polluted the environment as the carbon dioxide, sulfur toxic gases, among others. In this way, this "wastes" are the food of the bacteria and they can transform them into substances that are not harmful.
