Hint: Water is the vital source for the survival of all the organism. These water is available as the rain water, well water, pond, lake, sea, ocean, tank etc. Except sea and the ocean all the other water resources are available as freshwater resources.

Complete Answer:
- There were no water supply plants in the ancient times to deliver the water to the homes by using tubes and pipes. So people rely on the natural water resources for their needs.
- Water harvesting structures are constructed for the purpose of storing the water for the future use. In ancient times people used to collect the water from the rain or wells for their later purpose like drinking, taking bath, kitchen uses etc.
- The water in the river and the ponds depends on the amount of the rainfall received during the particular season.
- Hence in the extreme dry season, there will be no water in the river or the ponds, but few rains may occur at that dry conditions. So people harvest these water and store them in their home tanks for their later use when there is no water for their daily use.

Thus the option (A) is correct.

Note: In the later time, like the tank, the people also constructed the large water storage structures like dams, spillways, check dams, farm ponds etc. to save the water when excess and use it whenever it is necessary. However rainwater is the source of all water resources.
