Answer 1

Hint: Water is the most important substance on earth. Water is necessary for all living forms such as plants and animals. Water is an essential reactant in photosynthesis. Plants absorb water from the soil through roots. Animals and human beings require water for drinking and various other activities.

Complete answer:
To solve this question, we must know about the requirement of water by the United States.

The water is required for various activities like drinking and household needs, recreation, industry and commerce, agriculture and thermoelectric energy.

Water is also essential for maintaining hygiene like washing hands, bath etc.
The amount of water recommended by the US per person in a day is around 50 litres. This is equivalent to two and a half buckets of water.( Standard bucket size is around 20 litres).

In the US the FDA and Environment Protection Agency(EPA) is responsible for regulation of safety in drinking water. The tap water is checked by EPA whereas the FDA is responsible for packaged drinking water.

Hence, the correct answer is option (A)

Note: The United States uses around 322 billion gallons of water in a day. The 90%of the water is used for irrigation, thermoelectric power and in public supply.
