Answer :
The person might develop an intestinal infection from pathogens in the water.
Answer: Option (c) is the correct answer.
Explanation:
Since it is given that the water is untreated so there will be pathogens, that is, bacteria, viruses and other micro organisms might be there in the water.
Therefore, when a person drinks water it goes into the intestine and the contamination present in water will also go into the intestine. As a result, the pathogens present in water will cause intestinal infection.
Thus, we can conclude that most likely the person might develop an intestinal infection from pathogens in the water.
