Correct option is B
The correct answer is (B) 3%
The total amount of water on Earth is around 1.332 billion cubic kilometers, with only 3% being freshwater.
Of the 3% of freshwater, 2/3 is stored in glaciers and ice caps, primarily in Antarctica and Greenland.
The remaining 1% of freshwater is available in rivers, lakes, and reservoirs, making it accessible for consumption and irrigation.
Groundwater, which is a major source of freshwater, is found beneath the Earth's surface.
The availability of freshwater is crucial for drinking, agriculture, and industrial activities, making its conservation a priority.
