Solution

The correct option is A Only (i) and (ii)
The methods of water conservation are rain water harvesting and drip irrigation.
Drip irrigation - is a type of micro-irrigation that has the potential to save water and nutrients by allowing water to drip slowly to the roots of plants, either from above the soil surface or buried below the surface. The goal is to place water directly into the root zone and minimize evaporation.
Rain water harvesting (RWH) - is a technique of collection and storage of rainwater into natural reservoirs or tanks, or the infiltration of surface water into subsurface aquifers (before it is lost as surface runoff).
