D
97%
Explanation: 

Detailed explanation-1: -Over 97 percent of the earth’s water is found in the oceans as salt water. Two percent of the earth’s water is stored as fresh water in glaciers, ice caps, and snowy mountain ranges. That leaves only one percent of the earth’s water available to us for our daily water supply needs.

Detailed explanation-2: -97% of the earth’s water is found in the oceans (too salty for drinking, growing crops, and most industrial uses except cooling). 3% of the earth’s water is fresh.

Detailed explanation-3: -The vast majority of water on the Earth’s surface, over 96 percent, is saline water in the oceans.

Detailed explanation-4: -By far, most of the hydrosphere is salt water – around 97 percent – but the 3 percent that is fresh is critical for terrestrial and fresh water species.
