Given below are two statements, one labelled as Assertion (A) and the other as Reason (R). **Assertion (A):** The Karmnasa River is historically avoided by people for holy baths, and its name literally translates to 'destroyer of religious merit'. **Reason (R):** The river flows through highly industrial zones of South Bihar, making its water chemically toxic since ancient times. In the context of the above statements, which of the following is correct?

Options:

• A: Both A and R are true and R is the correct explanation of A
• B: Both A and R are true but R is not the correct explanation of A
• C: A is true but R is false
• D: A is false but R is true
