Given below are two statements. In the light of the above statements, choose the most appropriate answer from the options given below.
Statement I:Some microorganisms, especially protozoa, survive the conventional disinfection process.
Statement II:Some carcinogens, such as chloroform, are created during the chlorination process.
ABoth Statement I and Statement II are correct ✓ Correct
BBoth Statement I and Statement II are incorrect
CStatement I is correct but Statement II is incorrect
DStatement I is incorrect but Statement II is correct
Correct answer: (A) Both Statement I and Statement II are correct
Explanation
The first statement is correct that some microbes, notably protozoa, survive conventional disinfection.
The second statement is correct that carcinogens like chloroform arise during chlorination.
Hardy protozoan cysts such as Cryptosporidium resist standard chlorine doses.
Chlorine reacts with organic matter to form trihalomethanes including chloroform.
Both statements about disinfection limits are accurate.
This is why filtration and dose control accompany chlorination.
