Solution

The correct option is C Saline water > Frozen water > Usable surface water
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 all the freshwater, 68.7% is frozen, which is found in glaciers and ice caps. 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.
