b.) Drinking water
c.) Portable water
d.) Potable water

Answer 1

Hint: Potable water is the water which is filtered and treated properly and is finally free from all the contaminants and harmful bacteria.
We have been asked that water which is purified and fit for drinking is known as.
So, as we all know that water is the main source of life on earth. And our Earth has 71% water, but all this water is not fit for drinking purposes. So, to make water purify many steps are done like-

Complete step by step answer:
Purification of water involves-
Sedimentation- This process involves the settling down of the dirt particles and then the water is filtered such that the remaining particles are filtered out.
Filtration- In this process, the dirt particles, small pebbles are removed from the water.
Loading – In this process, there is loading of water into a container.
Chlorination – In this process, remaining microorganisms or any bacteria which may be still present after filtering also, are killed, so that the water is purified completely.
After doing all these processes, the water is made fit for drinking and is known as potable water.
So, the correct answer is “Option D”.

Additional Information:
The other process that are not fit to drinking water are given below:
the surface water pollution.
drinking water pollution in developing areas.
groundwater pollution with arsenic and fluoride.
illicit drugs in drinking water.

Note: Whenever such types of questions appear, then always first mention how the water is actually purified and made fit for drinking, as mentioned in the solution, all the steps done in the purification of water and then write the correct option.
