The correct answer is choice B. Nondisjunction.

Your town is planning on implementing a new wastewater reclamation plant (a connected wastewater plant and water treatment plant
Mazyrski [523]

The reasons why the wastewater reclamation plant will be implemented are the well-being of the environment, as well as making the water suitable for usage for the people. By installing the plant, the wastewater will be cleaned in most part. That will mean that the water can be returned to the nature without it causing damage to it and polluting it, but instead contributing to its well-being and proper functioning. Also, part of the water will be used for irrigation, as flushing water in the toilets, for doing laundry, which will result in preserving the freshwater reserves while still having a source of water for certain needs. The fact that the water will be cleaned, also means that the local water bodies will be safe to use for recreation, as they will not be polluted.
