Solution
The correct option is B Saline water > Frozen water > Usable surface water
Since oceans (which is saline in nature) are the biggest reservoir of water, containing about 97% of all the water present on the earth, these are the most available form of water on the earth. The second source of water, i.e., frozen water or ice is found on poles and mountains. The ice melts and feeds all the rivers which represent the usable surface water. Hence, the correct order is Saline water > Frozen water > Usable surface water
