• B. dissolved

Answer 1

Water that looks clean still has disease-carrying microorganisms and dissolved impurities.

Ways to treat water:

There are many ways in which the water can be treated that are discussed below:

Filtration:

• In the filtration technique, the solid impurities are completely taken out of the water through this process.
• For example, groundwater contains certain solid impurities that can be separated easily through the filtration process.

Boling:

• Boling is the best way to remove disease-carrying microorganisms or other impurities from the water.
• This can easily be done at home.

Chlorination:

• Chlorination is considered the best technique in which bacteria, viruses as well as other microorganisms are removed from the water via the addition of chlorine or chlorine compounds.

Thus, these processes are useful for treating water which makes it safer to drink as the water which looks clean still has certain disease-carrying microorganisms and dissolved impurities.
