Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
Water resources are categorized by color codes (Green, Blue, Grey, Black) and conceptual definitions (Virtual, Fossil) to optimize water footprints and conservation.
Step 3: Detailed Explanation:
- Green water (A): Rainwater stored as moisture in the unsaturated soil zone. It is the primary water source for dryland crops, grasslands, and forests (II).
- Fossil water (B): Deep underground aquifers formed over thousands of years. Extracted for intensive agriculture and domestic use (III) in arid regions.
- Grey water (C): Relatively clean domestic wastewater (from sinks, washing machines). Low in pathogens, making it ideal for home kitchen gardens and lawns (I).
- Black water (D): Highly contaminated toilet wastewater containing fecal pathogens. It must be treated (V) before reuse to prevent pathogens from entering the food chain.
- Virtual water (E): The hidden volume of water embedded in agricultural or industrial commodities. International trade of these goods represents virtual water transfer (IV).
Step 4: Final Answer:
The matching sequence is A-II, B-III, C-I, D-V, E-IV. This corresponds to option (D).
