The correct choice is the method of injecting chlorine prior to filters primarily to prevent algae and fungi growth in the water supply.

Injecting chlorine before the filtration process helps ensure that any potentially harmful microorganisms, including algae and fungi, are effectively neutralized before the water passes through the filters. This is crucial because algae can clog filters and reduce their efficiency, while fungi can lead to biofilm formation on the filter media, complicating the treatment process. By addressing these issues at this stage, the overall water quality is improved, and the operational efficiency of the filtration system is maintained.

While there are other methods of chlorine application with different goals, such as improving taste and odor or enhancing chlorine concentration, the specific focus prior to filtration is aimed at keeping the water free from microbial contamination, ensuring that the filters can operate effectively without interference from biological growth.
