Detailed explanation-1: -Most of the water on the Earth’s surface is found in oceans and seas, which constitute about 97% of the water on Earth. The rest 3% is present in rivers, glaciers and underground water.

Detailed explanation-2: -The ocean holds about 97 percent of the Earth’s water; the remaining three percent is found in glaciers and ice, below the ground, in rivers and lakes. Of the world’s total water supply of about 332 million cubic miles of water, about 97 percent is found in the ocean.

Detailed explanation-3: -About 71 percent of the Earth’s surface is water-covered, and the oceans hold about 96.5 percent of all Earth’s water.

Detailed explanation-4: -Earth’s fresh water : Of all the water that exists on our planet, roughly 97% is saltwater and less than 3% is freshwater. Most of Earth’s freshwater is frozen in glaciers, ice caps, or is deep underground in aquifers.

Detailed explanation-5: -The correct option is B oceans. More than 97% of the water present on the Earth is in the oceans and seas, and is too salty for human use. The remaining 3% of the water is in the form of ice sheets, glaciers, and is also present under the ground. A very small percentage is available as fresh water for human use.
