Answer 1

The correct option is C Flow of water when goods are traded

Tony Allan introduced the concept of virtual water. He propounded that when food or other commodities are traded from one place to another, there is also a hidden flow of water. For instance, when wheat grains are traded, the water meant to cultivate the wheat is accounted for. This water is referred to as virtual water.
