The correct response highlights that the presence of pathogens in treated wastewater significantly decreases its reusability. Pathogens, which include bacteria, viruses, and protozoa, pose serious health risks when present in water intended for reuse, particularly in applications such as irrigation, industrial processes, or even indirect potable reuse. If treated wastewater contains pathogens, it may not meet health and safety regulations, thus limiting its safe reuse.

In this context, the other options are not as pertinent because they do not address the primary concern associated with pathogens. While pathogens could potentially increase treatment costs due to the need for more rigorous treatment processes or additional disinfection methods, the key issue remains the safety and reusability of the water. It's essential for treated wastewater to be free from harmful pathogens to be considered safe for various applications. The presence of pathogens does not ensure that water is safe for drinking, conflicting with public health guidelines; thus, mentioning safety in regard to drinking water does not align with the crucial role of pathogen absence for water reuse. Moreover, stating that pathogens have no effect overlooks the significant implications they present for water safety and usability, making it an inaccurate choice.
