Introduction:
Drinking water is an essential part of our daily lives. It is the primary source of hydration and plays a crucial role in maintaining our overall health and well-being. Water exists in various forms, including liquid, steam, and ice. However, when we refer to drinking water, it is primarily in the form of a liquid.

Explanation:
Liquid:
Drinking water is typically found and consumed in its liquid form. It is the most common and easily accessible form of water for human consumption. Liquid water is clear, transparent, and flows freely. It is the state in which water naturally exists on Earth and is readily available from various sources such as taps, wells, rivers, and bottles.

Steam:
Steam is the gaseous form of water that occurs when liquid water is heated to its boiling point. While steam can be used for various purposes, such as generating power or cooking, it is not typically consumed as drinking water. Drinking steam directly can be dangerous and may cause burns or scalds.

Ice:
Ice is the solid form of water that occurs when liquid water is frozen. While ice can be used to cool beverages or preserve food, it is not considered the primary form of drinking water. However, ice cubes can be added to a glass of liquid water to make it colder and more refreshing.

Conclusion:
In conclusion, the correct answer is option 'A' - liquid. Drinking water is primarily consumed in its liquid form, which is safe, refreshing, and essential for maintaining proper hydration. While water can exist in other forms such as steam or ice, they are not typically consumed as drinking water.
