2. Which of the following is NOT a typical consequence of urban flooding in a metropolitan city like Delhi?
- A.Disruption of transportation networks and economic activities
- B.Increased incidence of waterborne diseases
- C.Significant decline in groundwater levels due to increased surface runoff
- D.Damage to infrastructure and property, leading to financial losses

3. Consider the following statements: Assertion (A): Unplanned urbanization contributes significantly to increased flood risk in cities like Delhi. Reason (R): Impervious surfaces like concrete and asphalt reduce infiltration and increase surface runoff. In the context of the above statements, which of the following is correct?
- A.Both A and R are true and R is the correct explanation of A
- B.Both A and R are true but R is NOT the correct explanation of A
- C.A is true but R is false

सही उत्तर: A
Both the assertion and the reason are true, and the reason correctly explains why unplanned urbanization leads to increased flood risk.
4. In the context of urban water management, what is the primary purpose of a 'detention basin' as often used in drainage master plans?
- A.To purify wastewater for reuse in irrigation
- B.To collect and store rainwater for drinking purposes
- C.To temporarily store stormwater runoff and release it at a controlled rate
- D.To generate hydroelectric power using the force of floodwaters
