The Correct Answer is: (b) 2.5%
Explanation:
Only 2.5% of the total water on Earth is freshwater, which is essential for drinking, agriculture, and other human needs. However, most of this freshwater is locked in ice caps,
glaciers, or underground aquifers, with a small percentage being readily accessible in rivers and lakes.
Information Booster:
97.5% of Earth's water is salt water.
Only 0.3% of the world's freshwater is easily accessible for human use.
Water conservation techniques like rainwater harvesting and water-efficient irrigation can help manage limited freshwater resources.
Groundwater: Around 30.1% of freshwater is stored as groundwater, of which a significant portion is difficult to access.
