Solution

The correct option is B Saline water > Frozen water > Usable surface water

Freshwater is naturally available water with very little salt in it. Out of all the water present on the Earth, 97% of it is saline and it is unfit for drinking and domestic use. Only 3% of the Earth’s water is freshwater. Out of 3% of freshwater, 68.7% is frozen, which is found in glaciers and icecaps. 30% of the freshwater is found under the ground and 0.3% is usable surface water which is found on the Earth's surface.
Hence option b represents the correct order of the relative amount of saline water, frozen water and usable surface water on the Earth.
