correct option is not mentioned

Step-by-step explanation:

Water covers approximately 71% of the Earth's surface. This includes the vast expanse of the oceans, which account for nearly 97% of all water on Earth. However, most of this water is saltwater.

Freshwater makes up a small fraction of the Earth's total water supply—only around 2.5%, and out of that, an even smaller amount is accessible for the human use, as much of the freshwater is trapped in ice caps, glaciers, and buried the underground.
