💡 Analysis & Explanation
Hydrological Context ▼
Irrigation sources are broadly classified into surface water systems and groundwater systems based on where the water is drawn from.
Option Assessment ▼
Ponds, tanks, and river canals all collect, store, or redirect surface water that is visible above the earth's crust.
Groundwater Access ▼
An open-well requires digging deep into the soil profile to access aquifers and water tables situated below the earth's surface.
Conclusion ▼
The open-well uniquely represents a groundwater-based source among the choices.
