Freshwater is characterized by having a Total Dissolved Solids (TDS) concentration that is generally low, making it suitable for various uses, including consumption. The correct choice indicates that freshwater has a TDS concentration of less than 1,000 ppm. This threshold helps differentiate freshwater from brackish or saline water, which typically contains higher concentrations of dissolved solids.

The TDS level is essential because it can affect the taste, usability, and overall safety of water for drinking and irrigation purposes. Water with a TDS of less than 1,000 ppm is often considered acceptable for human consumption and is usable for many ecological and agricultural applications.

Understanding this definition is crucial in various fields, including environmental science, hydrology, and public health, as it assists in determining water quality and management practices.
