Answer: (A)

In water treatment, how factors influence the outcome is about how they interact with one another. The result you see in water quality and plant performance is shaped by the combined effect of multiple variables, not by any single factor in isolation. For example, the way a coagulant dose works depends on pH and alkalinity; the same dose can yield different turbidity removal at different pH levels. Similarly, disinfection efficiency depends on chlorine dose, contact time, temperature, pH, and the amount of organic matter present—their interplay determines the actual effect and residuals. Because these outcomes arise from the interaction of several factors, the statement is true.
