Answer:
The letter C is the right answer.
Explanation:
According to salinity, we can divide the water into fresh, brackish and salty. Freshwater has a small amount of salt (less than 1%), so, despite the term, we must make it clear that it does not contain sugar. This is the water most used by man and is available in rivers, lakes and underground reserves. It is estimated that it represents only 2.5% of the total water on the planet.
