उत्तर

Both A and R are true but R is not the correct explanation of A.

Explanation:

Raw sewage contains human waste, which is a primary source of dangerous pathogens, including bacteria, viruses, fungi, and parasites. Therefore, Assertion (A) is true. 

Consuming water contaminated with these pathogens leads to severe waterborne diseases such as cholera, typhoid, and jaundice. Therefore, Reason (R) is true.

However, R does not explain A; it gives examples of diseases caused by contaminated water.

Hence, both A and R are true but R is not the correct explanation of A.
