Correct choice is (d) Metal extraction

Best explanation: Metal extraction is not the concern but it’s the solution to control ever increasing metal deposition in the environment, however, Eutrophication is a major concern which leads to algal blooms. Public safety and environmental protection are one of the major concerns and therefore removing phosphate from wastewater is very important.
