Given below are two statements, one labeled as Assertion (A) and the other labeled as Reason (R). **Assertion (A):** The state of Bihar receives the bulk of its annual rainfall from the Bay of Bengal branch of the Southwest Monsoon, primarily during July and August. **Reason (R):** During July and August, the axis of the Monsoon Trough (shifted ITCZ) lies over the Indo-Gangetic plains, directing cyclonic depressions from the Bay of Bengal into Bihar. 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.
