Answer 1

The most accurate response to why fresh water is a limited resource is:

Most water covering Earth is salt water.

This is because approximately 97% of the Earth's water is salt water, primarily found in oceans, leaving only about 3% as fresh water, much of which is not easily accessible due to being trapped in glaciers, ice caps, or deep underground.
