Which of the following is the best description of fresh water as a natural resource? a. unlimited and valuable b. limited and vulnerable c. vulnerable d. unlimited

B. Limited and Vulnerable because only a very small amount of water is available and its running out fast (For example: Cape Town, South Africa is in a drought and lost all potable water)

"Limited" would be the best description of fresh water as a natural resource, since it relies heavily on rainfall, which can be unpredictable and sporadic. It is also vulnerable to infestation, however.
