Given below are two statements, one labelled as Assertion (A) and the other as Reason (R).\n **Assertion (A):** The elimination of Kala-azar as a public health problem in Bihar relies heavily on vector control measures targeting the breeding sites of sandflies.\n **Reason (R):** Phlebotomus argentipes breeding sites are easily targeted because they breed exclusively in open, flowing water bodies like rivers and canals.\n Select the correct answer using the codes given below:

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
