Which of the following is considered an aesthetic quality of drinking water?

• A. Taste, color, and odor
• B. pH and alkalinity
• C. Turbidity and chlorine residual
• D. Dissolved minerals

Answer: (A)

Aesthetic quality refers to the sensory characteristics of drinking water—what it looks like and how it tastes and smells. Water that tastes, colors, or odors unpleasantly is less acceptable to consumers, so taste, color, and odor are the classic components of aesthetics. The other options describe chemical properties (pH and alkalinity), treatment/control indicators (turbidity and chlorine residual), or mineral content, which affect safety, stability, or composition rather than the immediate sensory experience.
