Which statement most accurately describes sewage?

The statement that sewage includes urine, feces, and wastewater is accurate because sewage is a broad term that encompasses various types of waste generated from human and household activities. This includes not only liquid waste but also solid waste components. Sewage typically originates from residential, commercial, and industrial sources, comprising not just human waste but also water that has been used for washing, cooking, and other purposes.

In contrast, the other options are too narrow or incorrect. The claim that sewage is exclusively liquid waste disregards the presence of solid materials found in sewage. Suggesting that sewage only refers to kitchen wastewater overlooks the wider range of inputs that contribute to sewage systems. Lastly, defining sewage as synthetic waste produced by factories misrepresents the nature of sewage, which primarily consists of organic waste from human sources rather than synthetic materials.
