What does 'domestic use' entail?

'Domestic use' specifically refers to the use of water for everyday purposes within a household. This includes activities such as drinking, cooking, bathing, washing dishes and laundry, and other personal hygiene needs. It encompasses all the water-related activities that are essential for the health and comfort of those living in a residential dwelling.

In contrast, the other options focus on distinct categories of water use. Agricultural purposes involve water for farming activities, which are broader in scope and do not pertain to individual household consumption. Industrial processes relate to water utilized in manufacturing or production, which again is outside the realm of personal use. Lastly, water for maintaining public parks falls under public or communal utility rather than the private or domestic sphere. Thus, the definition of 'domestic use' is clearly aligned with household activities, confirming the correctness of the selected answer.
