Correct option is D
Groundwater has several advantages, including:
1. A. It usually requires no treatment:
· Groundwater is naturally filtered as it passes through layers of soil and rock, making it generally clean and safe for consumption without extensive treatment.
2. C. It is likely to be free from pathogenic agents:
· The soil and rock layers act as natural barriers, reducing contamination and the presence of disease-causing microorganisms.
Explanation of Other Options: · B. It is high in mineral content:
· While groundwater often contains minerals, high mineral content (e.g., excessive iron or arsenic) is not necessarily advantageous as it can make the water unsuitable for drinking.
· D. It requires pumping to lift the water:
· While this is a feature of groundwater, it is not an advantage, as pumping increases costs and energy usage.
Correct Answer:
(d) A, C only
