Option A is correct.
Ozone is a highly unstable gas that breaks down rapidly into oxygen, often within a few seconds to 30 minutes, depending on the water chemistry.
This means it does not provide a residual disinfectant effect in the water as it travels through the distribution system to consumers. A persistent residual is essential to protect the water supply from potential recontamination in the pipes after leaving the treatment plant.
